Power Supply - SPS27W



The SPS27W is a fully adjustable output voltage power supply. The output voltage is normally preset at the factory, although it can easily be altered in the field. If this is done it is best to alter the output voltage under load.

The power supply is factory preset at the customer specified output voltage (between 1 and 30V DC). To determine the maximum current at any voltage for a continuous rating, refer to the graph below.
Current Rating Vs Voltage Graph
1V to 9V DC current max is 3A.
12V DC current max is 2.25A
Mains input is via a 3-pin plug and flex; output flying leads are provided outside the case (approx 2m long).
