Current, Voltage and Frequency Monitor

Measuring relays for current and voltage for installation in control cabinets ensure long-term reliability and resistance to interference by galvanic isolation between measuring and power supply circuits, and by using a power transformer with a low-capacitance split-bobbin winding. The shock-resistant fibreglass-reinforced plastic housing is fire-resistant and weather-proof. The devices can be snapped on to a standard mounting rail or secured with screws to a mounting plate. In addition, we manufacture measuring relays precisely according to your specifications.
