General Description
Overview
The 2001TRBP is a high-power transformer rectifier for powering outdoor warning
sirens. The 2001TRBP consists of an aluminum encased transformer with mounting
bracket. The 2001TRBP can be used as the only source of power for mechanical sirens
(AC operation). The 2001TRBP transformer operates from 208, 220, or 240 Vac, while
the 2001TRBP-480 operates from 416, 440, or 480 Vac. The transformer output is
46 Vdc at 130 A and 115 Vac at 10 A. The 46 Vdc is to power the mechanical siren and
the 115 Vac is used to power the siren control board, heaters, and chargers, if battery
equipped.
The 2001TRBP and 2001TRBP-480 includes a transfer relay contactor kit, which allows
primary operation from AC and battery backup when AC fails. The transfer relay kit
includes 48 Vdc contactor, buss bars, snubber and screws for attaching contactor to back
plate inside Federal Signal Control Cabinet.
