1900 Series

Switching DC Power Supplies

Discontinued Model 1902

Discontinued: April 4, 2017 MSRP $625 / 2 Yr Warranty
    • 1-60 V, 15 A Switching DC Power Supply
    • Model 1902B
    • 900W DC power supply with rotary encoder tuning for coarse and fine voltage and current control and dual LED displays to monitor output current down to 100 mA and voltage down to 100 mV

 Models 1900, 1901 and 1902 are are laboratory grade switching mode DC power supply with high current output in a small form factor and lightweight package. The supplies provide various configurations of high output voltage or high output current and make setting voltage and current levels fast and precise through its dual action, coarse/fine rotary encoder control. In addition to constant voltage (CV) and constant current (CC) modes, the high efficiency DC power supplies offer a unique solution with its preset and remote control modes. Save up to three different presets of voltage and current values for quick recall. The remote control function allows the output power, voltage, and current to be adjusted without touching the front panel of the power supply. A remote sensing terminal is also available for use to compensate for long output line losses. These features make the 1900 Series suitable for a wide range of applications including production testing, telecommunications, R&D, service, and university labs.

  • Automatic CV/CC crossover operation
  • Lightweight and compact
  • Rotary encoder control for precise voltage and current setting
  • 3 user-defined voltage and current presets
  • Remote control function
  • Remote sensing terminal
  • Overvoltage, overtemperature, and overload protection
  • Remote Sense (model 1900 only)

Ordering Information: Base models 1900, 1901, and 1902 operate with 110 V input only. For 220 V operation, request model 1900-220V, 1901-220V, or 1902-220V at time of order.
