Rectifier Panel for DC Brake – Construction, Adjustment & Voltage
Rectifier Panel for DC Brake Coils needs Dc supply for operation. DC Rectifier panel converts ac main supply to dc output supply. Typical application examples are E.O.T. Cranes, conveyors, rolling mills, etc.
Rectifier Panels are supplied with different combinations and can be offered for feed single or multiple brake coils.
The Standard Panels for Rectifier Panel for DC Brake
The Standard Panels can be offered for
Single brake operated individually, or
Two brakes operated individually, or,
Two brakes operated simultaneously.
Construction
Brake Rectifier panel is fabricated sheet steel enclosure and has two sections, the top compartment is for resistor assembly and bottom for controlling switchgear items like contractors, rectifier bridges, etc. The unit is designed for floor mounting. High-quality rectifiers have sufficient capacity to sustain over-voltage and current transients. Wound resistors have Nichrome/Eureka wires. The contractors and timers are of suitable ratings and are from reputed manufacturers.
Degree of Protection
The Standard Enclosure for rectifier unit conforms to the IP-54 degree of Protection as per IS:13947 (Part Ⅰ)-1993. The resistor unit is IP-23.
Finishing
Sheet Steel enclosures are given metal treatment for de-rusting, degreasing, phosphating prior to two coats of synthetic enamel paint.
