Constant voltage charging rectifiers for standby parallel operation, TR series

General

Secondary switched series with good efficiency and hardly noticeable noise emission. All device types of this series are full-load and short-circuit proof due to their electronic regulation, their voltage and current constancy is comparable to linear regulated devices. The TR series can be used for stand-by parallel operation for charging any lead and stationary industrial nickel-cadmium accumulators. The series is available in chassis (mounting plate for installation in switch cabinets), sheet steel housing and 19″ rack. On request, we will be pleased to offer you further versions, such as half load redundancy systems for increased reliability.

Standard equipment

Analog A-/V-meter Kl. 1% for the rectifier output Equipment (for chassis version at extra charge); input/battery/control circuit fuse (for 19″ devices, battery fuse by automatic double-pole in the front panel); protective isolation transformer according to VDE 0551; power switch/mains control lamp on the front of the housing; soft start; connection via screw terminals; cable feeds from the bottom or from the rear for 19″ racks.

Options

Temperature compensation of the charging voltage;
3 times switchable voltage level (continuous charge/ heavy charge/ equalizing charge).
Various other additional equipment such as fault alarm functions and distributions.
Versions

1. sheet steel housing with front door and double-bit locks; powder coating in RAL 7035; protection class IP31 (higher on request at extra charge)
