New from Adelsystem is the all-in-one family of uninterruptible DC power supplies. These offer reliable, consistent backup of the DC supply, and are ideal where frequent power outages or dips occur. They are particularly useful where there is a PLC or other digital communication.
The Adelsystem all-in-one is very flexible. Wide input voltage (115–230 V AC or 400–500 V AC) coupled with a selection of output voltages (12, 24 and 48 V DC) reduces the spares holding requirement. Different versions offer from 3 to 20 amps of current. Designed to offer safe operation, it has the following standard features: output protected against short circuit and overload; high insulation between primary and secondary; protection against deep battery discharge; protection against reverse polarity connection; and detection of batteries with incorrect voltage
The battery charging circuit contains charge curves for various types of batteries. These curves are user selectable by means of jumpers. Multistage charging (boost, trickle and recovery modes) ensures a fast recharge and also the recovery of deep discharged batteries. The maximum charging current to the battery is user adjustable by means of a potentiometer on the front of the unit. To protect the battery, the unit will shut down when the cell voltage reaches 1,5 V, avoiding deep discharge and battery damage. The unit also performs a battery life test to guarantee battery reliability. It continually tests the internal impedance of the cells and through a battery stimulation circuit is able to detect sulphated batteries and those with short circuit cells.
