Description

The Rish Master 3440 is versatile cost-effective solution for single and 3 phase networks. The Rish Master 3440 not only replaces multiple meters, it’s 96x96mm square cutout and a low back profile make it easy to integrate into your panel, especially if you are short on space. Once installed the Rish Master 3440 can be configured on-site or remotely via MODBUS (RS485) for maximum flexibility. The Rish Master 3440 is specifically designed to monitor and control power distribution systems by measuring more than 61 electrical parameters, storing max. and min. current and voltage values every 40 seconds, importing and exporting energy measurements of Active energy (kWh), Reactive energy (kVArh), Apparent energy (kVAh) and Ampere Hour (kAh) values and the ability to trip 2 relays if the measured values exceed the programmed High & Low Limits.

In case of power failure, the instrument memorizes the last energy count. The energy counter is updated every 40 seconds and saved to it’s non-volatile memory. The high brightness 3 line 4 digits LED, displays power values and can be set to auto scrolling or fixed screen mode via it’s front panel or remotely.
