Description


Demag GP 26089384 Brake Rectifier 110V-500V, ≤1.5A

Efficient voltage conversion from 110V to 500V with a maximum current handling of 1.5A for reliable industrial applications.

The Demag GP 26089384 brake rectifier is designed for efficient voltage conversion from 110V to 500V with a maximum current handling capability of 1.5A. This compact rectifier is ideal for industrial automation and control systems, ensuring reliable performance in demanding environments.

Engineer's Quick Brief

  • Ultra-Wide Voltage Compatibility: Rated for a massive AC input range of 110V to 500V, making it universally adaptable to global industrial power grids (from North American 120V/480V to European 400V systems).
  • High Current Capacity: Sustains a continuous output current of 1.5A, providing robust power conversion suitable for heavy-duty conical rotor motors and large cylindrical hoist brake coils.
  • Primary Application: Direct OEM replacement component for Demag Cranes, hoists, and material handling equipment to ensure reliable fail-safe electromagnetic braking.

Product Overview

The Demag GP 26089384 Brake Rectifier is a premium industrial solid-state power module engineered specifically for lifting and material handling technology. Manufactured by Demag Cranes & Components GmbH, this critical safety device converts alternating current (AC) from the main power supply into the direct current (DC) required to release the electromagnetic holding brake on hoist motors. Featuring a highly versatile input tolerance of 110V-500V AC and a robust 1.5 Ampere capacity, the 26089384 rectifier is heavily potted to withstand the severe vibration, dust, and temperature fluctuations inherent to overhead bridge crane operations.

Technical Specifications

Wiring Safety Note: Demag rectifiers are precision safety components. Always verify your specific motor's wiring diagram (typically located inside the motor terminal box cover) before applying power. Incorrect connection across the AC lines to the DC brake coil will cause catastrophic failure of the diodes.

Industrial Application Matrix

As a core component in material handling, the Demag 26089384 is utilized in safety-critical lifting applications:

  • Overhead Bridge Cranes: Controlling the main hoist and cross-travel trolley brakes to ensure precise load positioning and fail-safe holding during power outages.
  • KBK Light Crane Systems: Integrated into Demag chain hoists for ergonomic manufacturing assembly lines.
  • Heavy Winch Systems: Providing reliable DC actuation for heavy-duty friction brakes in steel mills and automotive plants.

Troubleshooting & FAQ

1. How do I test if my Demag 26089384 rectifier has failed?
Using a digital multimeter set to DC Voltage, carefully measure the output terminals connected to the brake coil while the AC power is applied (e.g., when pressing the pendant control). If your AC supply is present but the DC output is 0V or highly erratic, the internal diode bridge has blown. Always follow strict lockout/tagout (LOTO) procedures when dealing with crane electronics.
2. The crane motor hums but will not lift, and the brake smells like burning. Is it the rectifier?
It is highly likely. If the rectifier fails to output DC power, the mechanical brake remains engaged (locked shut by springs). The hoist motor attempts to drive against the locked brake, generating severe friction and heat. Immediately inspect the rectifier output and the physical brake air gap.
3. Can I use this on a 480V US power grid?
Yes, the Demag 26089384 is rated up to 500V AC input, making it fully compatible with 480V industrial grids. However, you must ensure that your hoist's brake coil is rated for the resulting DC voltage (typically around ~216V DC for a half-wave rectified 480V AC supply).

Cross-Reference Guide

If you are managing a fleet of lifting equipment, the Demag 26089384 (GP Series) shares operational envelopes with other premium industrial rectifiers. Verify mounting dimensions and current limits (1.5A) before substitution:

  • Demag Legacy Replacements: Often supersedes older blue or black Demag rectifier blocks with identical voltage ratings.
  • SEW Eurodrive Alternative: Similar to BGE or BG series brake rectifiers used in heavy gearmotors (ensure voltage/current match).
  • Lenze Equivalent: Standard half-wave modules utilized in automated braking applications.
