Wide-range output, multi-functional in one device

The output of the JBZ1000 series DC power supply adopts a 2.4-times wide-range output design. Under the rated output power, a single power supply can deliver voltage and current within a wider range, meeting the application scenarios of testing products with different voltage and current specifications. It effectively reduces the cost and space occupation of power supplies in laboratories or automated test systems.

Sequence Function

The JBZ1000 provides users with a sequence editing function that can simulate power supply interruption and instantaneous voltage drop of the device under test, as well as simulate other voltage and current variations. Each sequence file contains 100 steps and supports looping and linking, enabling users to easily output complex waveforms.

CV, CC take priority

When the power supply output is connected to an inductive or capacitive load, it will cause a certain degree of overshoot in the output current or voltage. In mild cases, it will trigger the protection of the device under test; in severe cases, it will directly damage the device under test. The JBZ1000 series is equipped with CV and CC output priority functions, which can effectively suppress output overshoot and its consequent impacts.

Battery Internal Resistance

The JBZ1000 series power supply is equipped with a battery internal resistance simulation output function. When the output current of the power supply increases, the output voltage can be adjusted according to the internal resistance value preset by the user.

Voltage slow rise and slow fall

The JBZ1000 series power supply facilitates users in testing the power supply stability of equipment. Users can complete tests ranging from several milliseconds to more than ten hours by configuring parameters such as time, slope, and voltage value according to testing requirements.

Rich external interfaces

The JBZ1000 series power supply is equipped with a rich set of interfaces for automation, integration and other applications. It comes standard with LAN Ethernet and RS232 communication ports, and optional interfaces such as CAN, RS485, trigger IO and analog monitoring can be flexibly configured according to customers' specific requirements. It supports protocols including SCPI, MODBUS and CANOpen.
