J. Schneider Elektrotechnik GmbH has added three models with 48 V output to the DC UPS series AKKUTEC.
The uninterruptible power supplies with 230 V AC input supply 48 V DC at the output , 1 A, 3 A or 10 A output current, depending on the model. Since the construction equipment is operated without a fan, they are extremely quiet and maintenance free. They are specially designed for installation in control cabinets.
All versions are real on-line DC UPS systems without switching. By the battery management via microcontroller (continuous battery monitoring and battery tests) relay contacts and deep discharge protection a high level of safety is maintained. The charging of batteries is temperature-controlled and thus easy on the batteries.
