Data Sheet Programmable DC Power Supplies Models 1696B, 1697B & 1698B The 1696B Series of compact 200 W DC power supplies are equipped with programming and protection features commonly found in more expensive performance instruments. Programming features include list mode for repetitive operation and 10 user-configurable voltage/current presets for quick recall. These benchtop power supplies also support adjustable voltage and current limits to protect the device under test. The front panel incorporates a numeric keypad, rotary control knob, and a dedicated V-set/I-set button for convenient control. The back-lit LCD simultaneously displays voltage, current, and power meter measurements with 4-digit resolution. This series features USB and RS485 interfaces for remote communication. Operating software is included for list mode set up and logging measurement data. Any of the three models in this series can be combined for multi-unit control of up to 31 power supplies. Features n Built-in n List voltage, current, and power meter mode (timed programming): program up to 20 steps n Automatic CV/CC crossover operation n Protection features: overvoltage (OVP), overcurrent (OCP), overtemperature (OTP) Applications Suitable for many applications including repetitive test routines in R&D, production testing, product evaluation, or in education environments. and key-lock function n Control up to 31 power supplies from one PC through RS485 n Store up to 10 voltage and current combinations for quick output n Lightweight n Large Model 1696B 1697B 1698B Voltage 1 to 20 V 1 to 40 V 1 to 60 V Current 0 to 10 A 0 to 5 A 0 to 3.3 A Max Output Power Technical data subject to change (c) B&K Precision Corp. 2019 200 W www.bkprecision.com and compact back-lit LCD display n Thermostatically-controlled fan with linear-speed control to minimize fan noise n USB and RS485 interfaces, supports basic SCPI commands Programmable DC Power Supplies Models 1696B, 1697B & 1698B Front Panel Back-lit LCD Rotary knob Adjustable brightness Quick and precise V & I control Keypad entry Input values directly and set up test sequences Output terminal block Isolated output supports banana plug or spade type connectors Rear Panel PC connectivity RS485 Multi-unit control for up to 31 power supplies nList mode (timed programming): Quickly set voltage, current, and duration for up to 20 steps nData logging function records voltage, current, and power measurements which can be exported in spreadsheet format 2 www.bkprecision.com Programmable DC Power Supplies Models 1696B, 1697B & 1698B Specifications Note: All specifications apply to the unit after a temperature stabilization time of 30 minutes over an ambient temperature range of 23 C 5 C.
