0 – 30V, 2A Dual Power Supply with Automatic Overload Protection

Scientech 4075

Share On:

 

Scientech 4075 DC Dual 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.
A special automatic overload (current) protection circuit limits the maximum current to 2 A. Two displays (one 3-digit display for voltage & other 3-digit for current) are used to read the values. These two can be switched simultaneously for either of the DC outputs.
Scientech 4075 has excellent line and load regulation and is provided with protective circuits to ensure trouble free operation.

Features

  • Pre-Regulator based design
  • Floating DC Supply Voltages
  • Dual DC : 2 x 0 – 30 V / 2 A
  • Automatic Overload (Current protection)
  • Constant Voltage & Constant Current operation
  • Digital display for Voltage and Current
  • Adjustable Current limiter
  • Excellent Line  & Load Regulation
  • Low Ripple Voltage
