AC STATIC RECTIFIERS
The AC Static/Rec ifier Controller is designed 10 operate the BE and BEM Type，AISE-NEMA shunt wound 50 volt DC shoe brakes installed on AC powered equipment. The basic unit
consists of a multi-tapped power transformer，bridge rectifier，
contactor，statlc control PCB and a protective circuit breaker，all
CON iROl CIRCUI1
mounted on a steel backing plate for pan自I mounting on customer's equipment. The unit is designed with a slalicliming ÀC CONNEC r'ON
circui，l which elìminates relay conlacls. The economizing circuil
reduces power ∞nsumptlon and assures fast brake release
when power is removed. The forcing circullassures faslbrake release when Ihe power is initially applied 10 the brake. AII models are equipped with a multi-tapped p吋mary lransformer for
230V， 460V and 575V slngle-phase power supplies.

These brakes are designed with a minimum number of parts 1.0 provide a long service life with reduced maintenance and downtime This versatìle brake can be applied to a wide range of applications and environmental conditions，where smooth， responsive stopping and holding is required. The cushioned brake action produces signmcantly less mechanical oscillations as compared to the DC Armature or the AC Solenoid type brakes. The latter are notoriously expensive to maintain in terms of spare parts and downtime.The inherent cushioning effect makes the brake ideal for high duty cycles or jogging applications，virtually eliminating mechanical shock loading which can lead to increased component wear and or component failures. Since the growth in popularlty of AC controlled cranes，this brake has rapidJy become the standard for all crane motions. It has the same high reliability that is normally associated with the DC Armature brakes，but does not require an expensive transformer/rectifier controller to supply the DC power.
