Voltech SPA-8230 User Manual

USER'S MANUAL / SPECIFICATONS

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 13.3 ~ 14.5V.
Constant current circuitry is used for overload, short circuit and over temperature protection. Output voltage will
reduce to a safety value when any of the faults occur and the DC output ON indicator will turn off. 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.

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 objects inside.
