Data Sheet High Power Switching DC Power Supplies Models 1900, 1901 & 1902 Full-Featured DC Power Supplies to Meet Your High Power Needs Features and Benefits Automatic CV (Constant Voltage)/CC B&K Precision models 1900, 1901, and 1902 its preset and remote control modes. Save up to are laboratory grade switching DC power three different presets of voltage and current (Constant Current) crossover operation supplies with high current output in a small, values for quick recall. The analog remote Up to 60 A output current lightweight form factor. The 1900 Series provide control function allows the output power, Lightweight and compact various configurations of high output voltage or voltage, and current to be adjusted without Rotary encoder control for precise voltage and high output current and feature rotary encoder touching the front panel of the power supply. A current setting control knobs, which make setting voltage and remote sensing terminal (model 1900 only) is Save up to 3 user-defined voltage and current current fast and precise. Its dual action push also available to compensate for voltage drop button allows the user to set both coarse and across load leads. presets for quick recall fine, voltage and current levels. Analog remote control function These features make the 1900, 1901, and 1902 Remote sensing terminal (model 1900 only) In addition to constant voltage (CV) and suitable for a wide range of applications requiring Overvoltage, overtemperature, and overload constant current (CC) modes, the high efficiency high current including production testing, protection DC power supply offers a unique solution with telecommunications, R&D, service, and Flexible operating modes: Front panel university labs.

These protections help prevent serious damage to equipment in case of power supply failure. Custom Presets Quickly use common voltage and current settings with a flip of the Recall preset switch. Up to three different presets can be set and recalled. Auxiliary output terminal Rear Control Indicator Analog Remote Control Capability Use the included connector to wire up to an external variable DC voltage source or variable Rear Panel resistor to remotely control the power supply s output voltage and current or to turn the Mode selection Main output switch Cooling fan terminal Recall preset switch output on/off. Remote Sense (Model 1900 only) Improve regulation of the power supplys output voltage at the load by using the Analog remote control terminal remote sense terminals to compensate for voltage drop across load leads.
