Manson Engineering Industrial SPA-8330 User Manual

INTRODUCTION

This fixed voltage switching mode power supply is designed with high RFI stability especially for DC operated radio equipment. It is also
suitable for a variety of applications that need a clean DC source.
The concealed trimmer allows fine tuning of output voltage range of 10 ~ 15V.
Constant current circuitry is used for overload, short circuit and over temperature protection. Output voltage and current would drop to a safety
value when any of the faults occur and the red indicator will turn ON. This power supply also has Over Voltage Protection to prevent your connected
equipment from damage by abnormal high output voltage.
Please read through this manual and pay special attention to the caution and safety precautions.
Keep this manual in an easy to find place for future reference.
CAUTIONS
DO NOT use this power supply for high inductive load such as solenoid or motorized equipment because of the inductive kick back from the output
may damage the power supply.
DO NOT operate power supply immediately with a newly replaced fuse before the fault has been found and rectified. Make sure to use the same
rating and type as the original fuse.

SAFETY PRECAUTIONS

Never remove the casing when the power supply is connected to AC or load.
Never touch the unit when your hands are wet.
Never block any of the grille openings or allow foreign object to get inside.
Must use a mains AC 3pin socket with effective grounding.
