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.

OPERATION 操作說明
The static rectlfier/controller shown in Fig. 1 is equipped with two eleclronlccircuits one for releasing Ihe brakes quicl<ly (forcin9) and energizing the brake ∞i1.When the AC vol is applied 10 the

Normally the inpullo the ansfoler L1and L2 would be connecled 10 the terrninals of the driving molor and the brake woutd opera!e when power is appiled 10 the molor.If desired the transforrner may be
