UPS Systems

The UPS-SYSTEMS ES1948-48V/39.6A is a switched mode rectifier (SMR) module designed to provide up to 39.6A of output current into a 48V nominal system. This rectifier has been designed especially to be used in conjunction with a battery to provide an uninterruptable DC power system. The low noise and high reliability make it ideally suited to telecommunications applications. The rectifiers are designed to slide and plug into a single magazine-SR1948-9 , designed for a 19” rack, which can accommodate up to 9 rectifiers and up to 32 rectifiers can be configured as a system using one control and supervisory unit (MCSU2048).

The UPS-SYSTEMS external battery charger is suitable for any 240Vdc system (20 batteries in series). It is designed for 240Vdc UPS systems to enable longer standby times for them. It can be used with PHD’s T3 Series (6-10kVA models) and T4 Series (10-20kVA models) Online Double Conversion UPS’s. It is easy to install as it is connected in parallel to the UPS’s existing battery charger.
