NICE / APOLLO MWSP-320-27, POWER SUPPLY AC/DC
The NICE Apollo MWSP-320-27 is a regulated AC/DC power supply used to provide 27 VDC power in compatible Nice Apollo and HySecurity gate operator control systems. In the field, this type of power supply is usually replaced when the operator has lost low-voltage DC output, the control box has suffered water or surge damage, the internal supply is visibly damaged, or the original supply tests outside the expected output range. It is a power component, not a control board, receiver, battery charger, or simple plug-in transformer.
Correct matching matters because gate operator power supplies are selected by output voltage, wattage, enclosure layout, connector style, grounding, and the control platform they feed. A supply with the wrong DC voltage or insufficient wattage can damage electronics, cause nuisance faults, or leave batteries and accessories operating incorrectly. This part should be matched to the original MWSP-320-27 label or to a current Nice Apollo/HySecurity parts diagram before installation.
Compatible With
Commonly associated with compatible Nice Apollo and Nice HySecurity systems that specify the MWSP-320-27 320W 27VDC power supply. Known references include MB1050 style AC control box assemblies and 1050-control-board based packages where the parts list calls out POWER SUPPLY, 320W 27VDC. It may also appear in selected HySecurity/Nice operator assemblies using the same 27 VDC supply platform. Verify by the original power supply label and operator parts diagram before ordering.

Technician Note
Check incoming AC voltage, DC output, fuse condition, battery condition, and signs of water intrusion before replacing the supply. A failed control board, shorted accessory, damaged wiring, or weak battery can mimic a bad power supply.
Before Ordering
- Match the original label to MWSP-320-27.
- Confirm the operator or control box parts diagram calls for 320W 27VDC output.
- Do not substitute for MX4859 or other AC transformers.
- Inspect for water damage, surge damage, and accessory shorts.
- Use a qualified technician for high-voltage wiring and startup checks.
Professional Advisory
Do not bypass fuses, grounding, or safety circuits while diagnosing power issues. If the operator has repeated power failures, have the complete system checked before installing a new supply.
Product Questions and Answers
What output does the MWSP-320-27 power supply provide?
The MWSP-320-27 is a 320 watt AC/DC power supply with 27 VDC output for compatible Nice Apollo and HySecurity gate operator control systems.
Is this the same as a standard gate transformer?
No. This is a DC power supply, not a simple low-voltage AC transformer. It should be matched to the operator parts diagram and original power supply label.
Which systems commonly use this power supply?
It is commonly associated with MB1050 style Nice Apollo control box assemblies and other compatible Nice HySecurity systems that specify a 320W 27VDC supply.
Can this be used in place of MX4859?
No. MX4859 is a 120 VAC to 19 VAC ACBOX transformer, while MWSP-320-27 is a 27 VDC power supply. They are different power components.
Who should install this power supply?
A qualified gate technician or electrician should handle replacement because the part involves line-voltage input and low-voltage DC output wiring.
