VOLTAGE STABILISERS
MINISTAB M
SINGLE-PHASE 230V 50/60 Hz, PROTECTION DEGREE IP21
Fittings: GC: range selector terminal block; L: pilot lamp
Optional fittings: V: digital voltmeter (M2..EV models)
Note: models with different power, and/or different input range, and/or different output accuracy can be quoted on demand
IREM voltage stabilisers are designed to deliver the declared power permanently (24/7) under the worst operating conditions, i.e. at full load, at minimum input voltage and max input current and at the declared ambient temperature.
