NORD Brake Rectifier Ghe40L
NORD Brake Rectifier Ghe40L – Half-Wave Motor Brake Rectifier Power Module
The NORD Brake Rectifier Ghe40L (part number 19141010) is an industrial-grade half-wave rectifier module designed specifically for controlling and operating electromechanical DC motor brakes across NORD DRIVESYSTEMS gearmotors and drives. Engineered to convert standard alternating current (AC) line power into stable direct current (DC), the NORD Brake Rectifier Ghe40L releases and engages magnetic brake coils in heavy-duty automated machinery.
As shown in the product image, the module features a vibrant yellow, high-impact plastic casing with a standard 6-terminal screw connector block on top, wire access points, and printed connection diagrams. Designed for mounting inside a motor terminal box, separate wiring enclosure, or control cabinet, this half-wave rectifier operates reliably under high ambient thermal loads.
Key Features of the NORD Brake Rectifier Ghe40L
-
Wide Permissible Input Voltage Range: Operates across input AC voltages ranging from 200V AC – 10% to 480V AC + 10% (50/60 Hz).
-
Proportional Half-Wave DC Output: Converts incoming AC voltage to DC voltage using a constant factor (U_DC = U_AC x 0.45), supplying 90–215V DC to the motor brake coil.
-
Configurable Switching Characteristics: Supports both Normal Switch-Off (AC-side switching for gradual deceleration) and Fast Switch-Off (DC-side switching via removal of the terminal 3–4 bridge for rapid braking).
-
Thermal Current Capacity: Handles up to 2.0 AÂ braking current at temperatures up to 40degree C, and 1.0 AÂ up to 75degree C.
-
High Switching Frequency: Rated for up to 1,800Â switching cycles per hour, making it suitable for continuous start-stop operations.
-
Compact, IP20 Enclosure: Features a compact footprint (35 g) with screw terminals supporting conductor cross-sections from 0.14 mm2 to 2.5 mm2 (26–14 AWG).
Common Applications and Industrial Usage
The fast response, thermal stability, and exact output conversion of the NORD Brake Rectifier Ghe40L make it an essential component across automated drive configurations:
-
Conveyor & Material Handling Systems: Controls holding brakes on belt, roller, and chain conveyors to prevent drift during pauses.
-
Hoists, Cranes & Elevators: Deployed using Fast Switch-Off mode (DC-side switching) to instantly apply emergency braking force on vertical lifting equipment.
-
Packaging & Processing Machinery: Provides repeatable brake actuation for precise indexers, filling stations, and automated packagers.
-
Industrial Automation & AGVs: Powers electromagnetic brakes on gearmotors, index tables, and automated guided vehicles.

Installation Guidelines and Best Practices
CRITICAL SAFETY NOTICE: Electrical installation and configuration of the NORD Brake Rectifier Ghe40L must only be performed by qualified electricians. Ensure power is fully disconnected prior to wiring.
Terminal Configuration:
Terminals 1 & 2: Connect to AC supply line (L1, L2).
Terminals 3 & 4: Keep factory bridge installed for Normal Switch-Off. Remove bridge and connect external contact for Fast Switch-Off.
Terminals 5 & 6: Connect to Brake Coil Positive (+) and Negative (–) respectively.
VFD Caution: Do not supply AC voltage to the rectifier directly from the output terminals of a Variable Frequency Drive (VFD). Supply line voltage separately.
To review official international motor drive standards and IEC semiconductor rectifier specifications for industrial equipment, consult the official IEC 60146 Semiconductor Converters Safety Standard Directory.
