Data Sheet Switching DC Power Supplies 1900B Series Full-Featured DC Power Supplies to Meet Your High Power Needs B&K Precision models 1900B, 1901B, and 1902B presets of voltage and current values for quick Features and Benefits are laboratory grade switching DC power recall. The analog remote control function allows n Automatic CV (constant voltage)/CC supplies with high current output in a small, the output power, voltage, and current to be (constant current) crossover operation lightweight form factor. The 1900B Series provide adjusted without touching the front panel of the n Up to 60 A output current various configurations of high output voltage or power supply. A remote sensing terminal (model n Lightweight and compact high output current and feature rotary encoder 1900B only) is also available to compensate for n Rotary encoder control for precise voltage and control knobs, which make setting voltage and voltage drop across load leads. current fast and precise. Its dual action push current setting button allows the user to set both coarse and These features make the 1900B, 1901B, and n Save up to 3 user-defined voltage and current fine, voltage and current levels. 1902B suitable for a wide range of applications presets for quick recall requiring high current including production n Analog remote control function In addition to constant voltage (CV) and testing, telecommunications, R&D, service, and n USB interface constant current (CC) modes, these high university labs. n Remote sensing terminal (model 1900B only) efficiency DC power supplies offer preset and remote control modes. Save up to three different n Overvoltage, overtemperature, and overload protection n Flexible operating modes: Front panel (normal), Preset, or Remote Control Model 1900B 1901B 1902B n Front panel 5 amp auxiliary output Variable Output Voltage 1 - 16 V 1 - 32 V 1 - 60 V Variable Output Current 0 - 60 A 0 - 30 A 0 - 15 A Technical data subject to change www.bkprecision.com B&K Precision Corp. 2016Switching DC Power Supplies 1900B Series Designed to Make Your Flexibility & Performance Work Easier Fully Protected LED indicators for Rotary encoder knobs for Have peace of mind knowing that these power constant voltage and quick and precise setting of supplies come with built-in OVP (overvoltage Bright, dual LED displays constant current modes voltage and current protection), OTP (overtemperature protection), and OLP (overload protection) circuitry. 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. Rear Control Indicator Auxiliary output terminal Rear Panel Analog Remote Control Capability Use the included connector to wire up to an Main output Recall preset external variable DC voltage source or variable terminal switch Cooling fan resistor to remotely control the power supplys output voltage and current or to turn the output on/off. PC Connectivity USB Analog remote Remote sense Mode selection Control your instrument through remote interface control terminal (Model 1900B only) switch control PC software or use programming commands to communicate with your instrument. 2 www.bkprecision.com
