Fittings: GC: range selector terminal block; L: pilot lamp
Optional fittings: V: digital voltmeter (T3..EV models)
Note: models with different power, and/or different input range, and/or different output accuracy can be quoted on demand.

irem-ecostab-sterostab 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.
