STUDER AJ SERIES
Sinewave Inverter with optional multi stage solar regulator

Studer Inverters

The Studer AJ true sinewave inverter- a high and steady efficiency has an outstanding overload capacity, thanks to the combined use of a toroidal transformer and a MOS power stage. It has a digital regulation and is microprocessor controlled. There is an electrical supply to any kind of electrical appliance and a complete internal protection of the inverter (overload, overheat, short-circuit, reverse polarity). Adjustable stand-by level on a large range and from a very low level (optional for AJ 275-350-400)

A floating 3 STEP (I/U/Uo) solar charge controller can be supplied built-in with the AJ. Making the inverter an "all in one" tool for solar systems. With this solar option the AJ 275- 350 and 400 have also a standby system.

Features :

- the inverter converts the battery voltage toAC voltage for all electrical appliances
- the high power charger supplies charge current to the battery
- the automatic transfer system manages the available power
- a high and steady efficiency
- an outstanding overload capability, thanks to the combined use of a toroidal transformer and a MOSpower stage
- an ultra-fast regulation and a control by microprocessor
- an electrical supply to most kinds of appliances
- a complete internal protection of the Invertercharger (overload, overheat, short-circuit, reverse polarity)
- a stand-by level adjustable on a large range and from a very low threshold on
- no noise thanks to HF-switching > 20kHz
