Scientech 4074 Multiple Outputs 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 0-30 V and 0 ±15 V dual tracking can be adjusted, with coarse and fine controls. DC output 5 V can be adjusted between 4.8 V – 6 V. Current limit is adjustable from 0-1A. Over loading is indicated by LED. After crossing the specified limit a audible beep will sound.
A 3-digit display for voltage and 3 ½ digit display for current is provided to read the values. These two parameters are can be switched to display either voltage or current.
Scientech 4074 has low ripple and excellent line and load regulation and is provided with protective circuits to ensure trouble free operation.
