Frequently Asked Questions - EDR-120-24 Mean Well
What is the output voltage of the Mean Well EDR-120-24?
The output voltage is 24 VDC with an adjustment range of 22.8 to 26.4 V.
What is the maximum output current?
The maximum output current is 5 A.
Can the EDR-120-24 be used with 110V or 220V input?
Yes, it accepts a universal input voltage range of 85 to 264 VAC at 47-63 Hz.
How do I mount the power supply onto a DIN rail?
Clip the unit onto a TS-35/7.5 or TS-35/15 DIN rail. Ensure the rail is properly grounded and the unit snaps firmly into place.
What protections does the EDR-120-24 have?
It includes short circuit, overvoltage, and overload protections with automatic recovery after fault removal.
Is the power supply suitable for outdoor use?
No, it has an IP20 rating, meaning it is only protected against solid objects larger than 12 mm and is not waterproof. Use indoors or inside an enclosure.
What is the operating temperature range?
It can operate from -20°C to +60°C, but output power must be derated above 50°C.
How do I adjust the output voltage?
Locate the trim potentiometer on the unit (marked VADJ) and turn it gently with a small screwdriver to set the voltage between 22.8 and 26.4 V.
Will the EDR-120-24 work with a dimmer or phase-cut controller?
No, this is a standard AC-DC power supply and should not be used with dimmers. It requires a clean AC input.
Can I connect multiple units in parallel for higher current?
Parallel operation is not recommended. For higher current, use a single supply with higher rating or consult the manufacturer.
