I-V characteristic function
By registering multiple arbitrary points on the I-V characteristics, arbitrary I-V characteristics can be set for each CC and CV operation mode. Arbitrary points can be registered from 3 to 100, making it possible to simulate the I-V characteristics of rechargeable batteries and other devices.
Reliable and solid performance even under high temperatures
Solid performance under operating temperatures of 0°C to 50°C. Exhibits full performance even in environments with severe ambient temperatures, such as when installed in equipment.
Caution: PXB20K-50 and PXB20K-250 operates in the temperature range of 0°C to +40°C.
Protection Functions for Safety Operation
- OVP (Over voltage protection)
- UVP (Under voltage protection)
- WDOG (Communication error protection)
- OPP (Over power protection)
- OCP (Over current protection)
- EXT LOW (External input alarm detection)
Priority Operation Mode
Mode of operation can be set, as constant voltage (CV), constant current (CC), or constant power (CP), when output is turned on. Overshoot can be prevented by setting CC mode priority when batteries, power supplies, etc. are connected.
External Control Function
The EXT CONT connector on the rear panel can be used to control the PXB series with external devices. The general-purpose digital input and output terminals can be assigned any function, facilitating system construction in combination with other measurement devices.
Digital I/O standard for both NPN and PNP type PLCs. Analog I/O is isolated from output terminals as standard, allowing safe analog control from PLC.

*1. Does not apply to specially ordered or modified products. *2. Only for models with CE marking / UKCA marking on their body. *3. This is a Class A instrument. This product is intended for use in an industrial environment. This product may cause interference if used in residential areas. Such use must be avoided unless the user takes special measures to reduce electromagnetic emissions to prevent interference to the reception of radio and television broadcasts. *4. This is a Class I instrument. Be sure to ground this product’s protective conductor terminal. The safety of this product is guaranteed only when the product is properly grounded. *5. Pollution is addition of foreign matter (solid, liquid or gaseous) that may produce a reduction of dielectric strength or surface resistivity. Pollution Degree 2 assumes that only non-conductive pollution will occur except for an occasional temporary conductivity caused by condensation. *6. Only on models that have cTUVus marking on the panel.
