Scientech 4077 Multiple DC Power Supply is designed as a Constant Current (CC) and Constant Voltage (CV) source source for use in laboratories, industries and field testing. With compact size, light weight and required for low power loss, it provides DC output voltages for Analog and Digital testing.
A 3-digit display for voltage & 3-digit for current is provided to read the values. These two parameters are switchable for indicating either voltage or current.
Scientech 4077 has excellent line and load regulation and is provided with protective circuits to ensure trouble free operation.
