Highly efficient power supply and backup power supply solutions to telecommunications, information and industrial technologies.


Battery tester RZ-80

The RZ-80 Regulated Load is suitable for testing of NiCd, Pb, NiMh 1.2, 2, 4, 6, 8, 10, 12 and 16 V battery cells with a nominal voltage between 24 VDC and 48 VDC. Its compact size and low weight make it ideal for everyday use, especially in confined spaces.

Values available during measurement

  • Passed and remaining time of capacity testing
  • Total voltage of battery string
  • Actual current
  • Actual power
  • Discharged capacity
  • Temperature measured by each module
  • Voltage of individual battery blocks (possible to sort by order or voltage)
  • Possibility to read and change selected parameters

Values available after measurement

  • Possibility to read the values of individual measurements and change parameters directly on the display, without the need of a PC when in the field
  • Overview of memory usage

 Universal use

  • Wide range of input voltage from 20 to 60 VDC
  • Compact size and low weight
  • Allows for use of up to 12 measurement modules with a total of 288 inputs for measuring the voltage of battery blocks
  • Possible to use also without measurement modules (e.g. testing load for DC power systems)
  • Minimized conductor length and improved safety thanks to wireless data transfer among modules
  • Possibility to change the number of measurement modules prior to the start of capacity testing
  • Maximum time of measurement up to 24 hours
  • Easy and intuitive control
  • PC connection via USB
