The programmable bidirectional DC power supply DS91000 series is a bidirectional system that integrates DC feedback load and DC source functions. This series can calculate voltage, current testing, active power, reactive power, and power factor.
This series can be used for the evaluation and testing of battery systems, power equipment, electric motors, elevators, cranes, light rail, hybrid power components, simulation of vehicle and aircraft wiring systems, electronic process confirmation of process technology, inspection and cyclic testing of energy buffering systems. Assist manufacturing enterprises in saving testing time and improving batch production efficiency.
Features
• Dual mode operation of power load.
• The DC source mode has a constant voltage and current function, and the voltage and current can be adjusted.
• The maximum output current can be set in constant voltage mode.
• The maximum output voltage can be set in constant current mode.
• In constant voltage output mode, when the constant voltage output is exceeded, it switches to constant current mode.
• In constant current output mode, short-circuit testing can be performed to ensure a constant current. When the constant current output is exceeded, it switches to constant voltage mode.
• The whole machine has manual control and program control functions.
• It has reverse sequence detection, overcurrent, overvoltage, overload, and short-circuit protection functions.
• Power access and output interface, with electrical safety protection function.
• Read DC output voltage, current, and equipment fault information through GPIB/RS232 communication.
• Under the feedback load mode, the device has CC and CV loading modes.
