Features digital control interface, precision voltage regulation, adjustable current limiting, and overload protection. Can operate in constant voltage or constant current mode with remote sensing capability. Provides isolated outputs with low ripple and noise characteristics. Includes digital readout for monitoring voltage and current settings. Suitable for testing power-hungry components, battery charging, and electroplating processes. Designed for bench-top or rack-mount integration with cooling system to support continuous operation at maximum ratings. ## Function Provides adjustable DC power with high current output. Offers constant voltage (CV) and constant current (CC) modes. Includes overvoltage, overcurrent, and overtemperature protection. Features remote sensing to compensate for voltage drop. Designed for benchtop or rack-mount operation. Interfaces via front panel controls and rear panel terminals. Suitable for powering electronic circuits and automated test equipment. ## Platform The 1901 is a programmable switching DC power supply designed for high-power applications requiring precise voltage and current control. It operates on standard AC mains power (110-240VAC, 50/60Hz) and provides a single isolated DC output channel with wide adjustment ranges. The unit interfaces through front panel controls with rotary encoders and keypad, remote analog programming via rear panel terminals, and digital communication using RS-232 and USB ports supporting SCPI command protocol. Optional GPIB interface enables integration into automated test systems. The supply features remote sense terminals to compensate for voltage drops in load leads, parallel/series operation capability for increased current/voltage, and trigger input/output for synchronized testing. Common applications include burn-in testing, battery charging and formation, electroplating processes, DC motor testing, magnet charging, semiconductor characterization, and general laboratory use requiring stable high-power DC sources. ## Application Precision testing and development of electronic circuits and devices requiring stable, high-current DC power; use in laboratories for powering RF components, motors, and power amplifier modules; integration into automated test systems via standard interfaces; suitable for system bench setups demanding adjustable voltage and current with high efficiency and low ripple noise. ## Accessories Optional Rackmount Kit RK-1900. Interfaces: Front panel high-current binding posts for positive/negative DC output and a chassis ground binding post. Rear panel includes an IEC 320-C14 AC power inlet, a 2-position screw terminal block for remote sense connections (S+, S-), and a DB-9 female connector for analog remote control of voltage, current, and output on/off status. ## Images - - - -
