SL Power GPC41-12 12V 40W AC/DC Power Supply

Description

Key Technical Specifications

The original SL Power/Condor datasheet specifies the GPC41-12 at 12 V, 3.3 A, with a 0.03 A minimum load, 0.75% load regulation, ±2% initial setpoint tolerance, and 1% ripple/noise.

The same datasheet specifies a universal input range for the GPC41 family and a maximum physical height of 1.50 in. The power supply is an open-frame design intended for chassis mounting rather than a DIN-rail power supply.

Important G-Suffix Note

Do not confuse GPC41-12 with GPC41-12G. The manufacturer’s documentation states that the “G” suffix identifies the RoHS-compliant model. The base GPC41-12 is documented as the non-RoHS version.

Product Introduction

The SL Power GPC41-12 is a 40 W open-frame AC/DC switching power supply that converts 85–264 VAC input to a regulated 12 VDC output at up to 3.3 A. Its 4.00 × 2.00 × 1.50 in. chassis-mount format makes it suitable for equipment where an internal PCB-style power supply is required.

For replacement work, the key parameters are the 12 VDC output, 3.3 A capacity, universal AC input, mechanical dimensions, terminal/pin arrangement, and minimum-load requirement. The -12 is an obsolete product, so the exact suffix and physical configuration should be checked against the installed unit before substitution.

Installation & Configuration Guide

Step 1 — Verify the Replacement

Before removing the existing power supply:

1. Confirm the complete part number is .
2. Check whether the installed unit is actually or .
3. Record the input and output wiring.
4. Measure the available installation space.
5. Confirm the mounting-hole pattern.
6. Check the equipment’s required output current.

Warning: A physically similar 12 V power supply is not automatically a suitable replacement. The output voltage, current, minimum load, protection characteristics, connector/pin arrangement, and mechanical envelope must all match the application.

Step 2 — Shut Down and Isolate

1. Shut down the host equipment according to its maintenance procedure.
2. Disconnect the upstream AC source.
3. Apply appropriate lockout/tagout procedures.
4. Verify that hazardous voltage is absent.
5. Allow internal capacitors to discharge before handling the PCB.
6. Use ESD precautions when handling the open-frame supply.

Step 3 — Remove the Eng

1. Photograph the original wiring.
2. Label each AC and DC conductor.
3. Disconnect the input and output wiring.
4. Remove the four mounting fasteners if fitted to the chassis.
5. Lift the power supply clear without contacting exposed components.
6. Compare the old and replacement boards side by side.

The mechanical documentation specifies four mounting locations and a maximum height of 1.50 in. (38.10 mm).

Step 4 — Install the Replacement

1. Posithe in the original mounting location.
2. Confirm adequate clearance around the heatsink area.
3. Secure the board using the appropriate hardware.
4. Reconnect the AC input exactly as documented by the equipment manufacturer.
5. Reconnect the 12 VDC output.
6. Check polarity before applying power.
7. Inspect all wiring for accidental shorts or exposed conductors.

Step 5 — Power-On Test

1. Energize the AC input with the equipment disconnected from sensitive loads where practical.
2. Measure the DC output.
3. Confirm approximately 12 VDC under the specified operating conditions.
4. Connect the downstream load.
5. Check the output again at normal operating load.
6. Monitor for excessive temperature rise, audible noise, or unstable output.
7. Verify that the host equipment starts normally.

Engineering Notes

he has a documented minimum load of 0.03 A. If the downstream equipment draws less than this value, verify the supply’s behavior under the actual system load rather than assuming that no-load operation is acceptable.

The manufacturer’s environmental notes also specify output-power/current derating above 50°C and recommend adequate airflow in confined installations.

FAQ

What is the output of the Ser ?

he provides 12 VDC at up to 3.3 A, with a rated output of approximately 40 W.

What is the input voltage range?

The documented input range is 85–264 VAC, making it a universal-input AC/DC supply.

Is a DIN-rail power supply?

No. It is an open-frame chassis-mount power supply. Its documented dimensions are 4.00 × 2.00 × 1.50 in.

What is the difference en and -12G?

The manufacturer’s datasheet states that the G suffix denotes the RoHS-compliant version. Thee, and -12G should not be treated as identical ordering codes when compliance requirements matter.

he discontinued?

Yes. Current component databases identify as obsolete, and industrial replacement suppliers list it as discontinued.

What is the operating temperature?

The standard component specification lists 0°C to 50°C operating temperature. The manufacturer’s documentation states that output current and total output power must be derated by 2.5% per °C above 50°C.

Can I ce with another 12 V / 40 W supply?

Potentially, but the replacement must match more than the nominal output. Verify 85–264 VAC input, 12 VDC output, at least 3.3 A capacity, minimum-load behavior, mounting dimensions, mounting-hole pattern, wiring/pinout, thermal clearance, and applicable safety/compliance requirements before substitution. The oal is an open-frame supply, so enclosure and electrical safety provisions are part of the system design.
