Accessories for energy measurement technology

TOPJOB® terminal block with convenient operation and precise display of the switching status. Simple short-circuiting of current transformers.

The TOPJOB®S terminal block enables current and voltage transformers to be connected, current transformers to be short-circuited and voltage to be tapped and disconnected. Suitable for DIN35 mounting rails, high functionality with small dimensions.

Primary switched-mode power supply for protection class II devices. Self-cooling and suitable for installation and system distribution boards. Parallel switchable, series switchable and with galvanically isolated output voltage (SELV) in accordance with EN/UL 60903.50.

Galvanically isolated power supply unit for universal measuring devices with CAT IV supply voltage in accordance with IEC 61010-1 for environments with high short-circuit energy.

The IoT LoRaWAN interface enables the connection of all Modbus RTU devices such as universal measuring devices and energy meters from PQ Plus. Wireless configuration, open software interfaces and simple integration into new and existing LoRaWAN infrastructures.

The buffered DC power supply of the GC-UC243 series has an ultracapacitor inside the housing as an energy store.

The flexible PFS NH fuse-switch disconnectors enable versatile connection options. The integrated current transformers with a secondary signal of 333 mV provide the ideal basis for the modular outgoing metering system. Current transformers with other secondary signals and calibrated transformers are also possible. They are suitable for both 400 V and 690 V and thus enable the acquisition of extended measuring ranges.
