Electrical Specifications

Output Power Calculation

The relationship between voltage, current and power is:

Power = Voltage × Current

Therefore:

36V × 10A = 360W

This corresponds to the module's published maximum output rating.

Protection Features

Protection circuitry provides an additional safety layer but does not replace correct wiring, earthing, fusing, enclosure design or load selection.

Thermal Management

Output Characteristics

The module is intended to provide:

36V DC regulated output

for compatible equipment.

The connected load determines the actual current drawn.

For example:

36V × 2A = 72W

36V × 5A = 180W

36V × 8A = 288W

36V × 10A = 360W

The load does not automatically receive 10A; it draws current according to its electrical requirements, up to the capability of the power supply.

Important Rating Note

The published maximum rating is:

36V / 10A / 360W

For demanding continuous installations, thermal conditions, airflow, ambient temperature, wiring and load behaviour should all be considered rather than designing solely around the headline maximum rating.

36V DC

with a total current requirement of up to:

10A

and total maximum load up to:

360W

Input Compatibility

Supported mains input:

100V–240V AC, 50/60Hz

This allows operation across a wide range of compatible AC mains systems when correctly installed.

Output Compatibility

Fixed output:

36V DC

Maximum published output current:

10A

Maximum published output power:

360W

Important Purchase Note

This product is an open-frame AC-to-DC SMPS module, not a complete enclosed plug-and-play adapter.

A typical installation requires:

AC Mains → Fuse / Switch → SMPS → 36V DC Load

Appropriate protective enclosure, insulation and earthing should be incorporated into the final system.

High-Voltage Warning

Parts of the PCB and input terminals may be at dangerous mains voltage whenever AC power is connected.

The module should not be operated where users can accidentally touch the AC input or exposed high-voltage circuitry.

Product Variation

PCB layout, heat-sink finish, capacitor brands, terminal design and minor component placement may vary between manufacturing batches while maintaining the specified electrical function.

Getting Started

This module operates directly from AC mains voltage.

Installation should be performed only by a person familiar with mains-voltage electrical safety.

Step 1 — Confirm the Load

Before installation, verify that the equipment requires:

36V DC

and does not exceed:

10A / 360W

Step 2 — Check the Equipment's Voltage Rating

Do not connect the SMPS to equipment with a maximum voltage below 36V.

For example:

36V-rated equipment → Potentially Compatible

24V maximum equipment → Not Compatible

Step 3 — Keep AC Power Disconnected

Complete all wiring with mains power fully disconnected.

Never modify wiring while the SMPS is energised.

Step 4 — Identify the Terminals

Identify the AC-input and DC-output terminals using the markings on the actual module.

Do not rely on wire colour or assumptions.

Step 5 — Install Inside a Protective Enclosure

Because the module contains exposed mains-voltage circuitry, install it in an appropriate enclosure that prevents accidental contact.

Maintain ventilation around both aluminium heat sinks.

Step 6 — Use Proper Input Protection

A professionally designed installation should incorporate appropriate:

• Fuse protection

• Power isolation

• Insulation

• Earthing where applicable

• Strain relief

• Terminal protection

according to the final system design.

Step 7 — Verify Wiring Before Power-Up

Check:

• AC input connections

• Protective earth where applicable

• DC output polarity

• Terminal tightness

• Exposed conductors

• Insulation

• Load compatibility

Step 8 — Power the SMPS Without the Expensive Load

For initial testing, avoid immediately connecting an expensive amplifier or controller.

Apply power only after the module is safely enclosed or otherwise protected from accidental contact.

Step 9 — Measure the DC Output

Using an appropriately rated multimeter, verify approximately:

36V DC

at the output.

Step 10 — Disconnect AC Power Again

After verification, disconnect mains power and allow the supply to discharge before changing connections.

Step 11 — Connect the Load

Connect the compatible 36V load using appropriately rated output wiring.

Observe correct DC polarity.

Step 12 — Final Test

Power the system and monitor:

• Output stability

• Load operation

• Wiring temperature

• Terminal temperature

• Heat-sink temperature

• Ventilation

Important

Never work on the module while AC mains power is connected.

Even after switching off the supply, internal capacitors can retain electrical charge for a period of time.

🔧 Prototyping and Engineering Tips from RoboGears

1. Verify 36V Compatibility First

Never choose a power supply based only on current or wattage.

The connected device must first support:

36V DC

A 36V / 10A supply is not suitable for a board whose maximum permitted input is only 24V or 30V.

2. Understand the 10A Rating

The SMPS can supply up to its rated current according to load demand.

A 2A load does not automatically receive 10A.

At 36V:

2A ≈ 72W

5A ≈ 180W

10A = 360W

3. Use Heavy-Gauge Output Wiring

At high current, undersized wire causes:

• Voltage drop

• Heating

• Power loss

• Reduced amplifier performance

Use appropriately rated wiring for the expected current and cable length.

4. Keep DC Wiring Short

For high-current amplifier applications, keeping the 36V output wiring reasonably short helps reduce voltage drop.

5. Provide Proper Ventilation

The SMPS uses large dual aluminium heat sinks.

Do not install the supply in a completely sealed enclosure without suitable ventilation.

6. Keep the Heat Sinks Clear

Allow airflow around the heat sinks.

Avoid placing:

• Foam

• Wires

• Insulation

• Other circuit boards

directly against the heat-dissipation surfaces.

7. Verify Output Before Connecting Expensive Equipment

Before connecting an amplifier, CNC controller or robotics system:

Measure the output with a multimeter.

Confirm correct voltage and polarity first.

8. Protect the AC Side

A properly engineered installation should use suitable:

• Fuse protection

• Power switch / disconnect

• Earthing

• Insulation

• Cable strain relief

according to the final equipment design.

9. Cover Exposed AC Terminals

Open AC terminals create a serious shock hazard.

Use a suitable enclosure or terminal protection to prevent accidental contact.

10. Keep Mains and Low-Voltage Wiring Separated

Inside an enclosure, maintain sensible physical separation between:

• AC input wiring

• 36V DC output wiring

• Low-level audio wiring

This improves both electrical safety and noise performance.

11. Audio Projects Benefit From Good Wiring Layout

When powering amplifier boards:

• Keep AC wiring away from audio signal wiring

• Keep high-current DC wiring short

• Maintain secure ground connections

• Avoid unnecessary cable loops

This can help minimise unwanted hum and noise.

12. Don't Assume Every 360W Amplifier Needs 360W Continuously

Music has varying instantaneous power demand.

The actual power required depends on:

• Amplifier architecture

• Speaker impedance

• Output level

• Number of channels

• Audio programme material

Select the supply according to the actual amplifier requirements.

Troubleshooting

No 36V Output

With AC power safely isolated, check:

• Input wiring

• Fuse/protection

• Terminal connections

• Load condition

Do not troubleshoot exposed mains circuitry while energised.

Output Drops Under Load

Possible causes include:

• Excessive load current

• Poor DC wiring

• Loose terminals

• Over-current protection

• Thermal conditions

Amplifier Distorts at High Volume

Check:

• Amplifier voltage compatibility

• Current demand

• Speaker load

• DC wiring

• Terminal connections

SMPS Gets Very Hot

Check:

• Load current

• Ventilation

• Heat-sink airflow

• Installation enclosure

• Terminal condition

Wiring Gets Hot

Stop operation and inspect:

• Wire gauge

• Connectors

• Terminal tightness

• Load current

Hot wiring can indicate excessive resistance or undersized conductors.

Protection Activates

Investigate possible:

• Output short circuit

• Excessive current

• Incorrect load

• Wiring fault

Do not repeatedly reset the supply without identifying the underlying problem.

Engineering Principle

A reliable high-power DC supply system requires correct matching of:

AC Protection + SMPS + DC Wiring + Load + Cooling + Enclosure

Correct voltage selection and safe mains installation are more important than simply choosing the highest available wattage.
