0 – 30V – 3A DC Power Supply

Scientech 4078

Share On:

 

Scientech 4078 DC Power Supply is designed as a Constant Current (CC) and Constant Voltage (CV)source for use in laboratories, industries and field testing. With compact size, light weight and low power loss it, provides DC output voltages for Analog and Digital testing.
The DC output can be adjustable from 0 – 30 V with Coarse and Fine controls. Current limit is adjustable from 0 – 3A. Over loading is indicated by LED.
A 3-digit LED display for voltage & current is used to read the values. These two parameters can be switched to display either voltage or current.
Scientech 4078 has excellent line and load regulation and is provided with protective circuits to ensure trouble free operation.
