RECTIFIER

Product Description

The Kito Rectifier is a genuine OEM replacement electrical component designed for use in Kito EC Series electric chain hoists, identified by part number ECP93DIAA. The rectifier is an internal electrical component of the hoist brake circuit, converting alternating current (AC) from the hoist power supply to direct current (DC) to energize the electromagnetic brake during hoist operation. The electromagnetic brake on an electric chain hoist relies on a stable DC supply from the rectifier to release and engage correctly during lifting and lowering cycles, and a failed or degraded rectifier will result in incorrect brake behavior that can compromise the safe holding and controlled lowering of suspended loads.

The rectifier is subject to degradation over its service life through thermal cycling, voltage transients, and the cumulative effects of industrial operating environments including heat, vibration, and humidity. Common failure modes include open circuit failure resulting in the brake failing to release when the hoist is energized, short circuit failure resulting in the brake failing to engage when the hoist is de-energized, and partial degradation resulting in reduced DC output voltage that causes sluggish or inconsistent brake engagement and release. Any of these conditions require the hoist to be removed from service until the rectifier is tested and replaced by a qualified hoist technician with electrical competency in hoist brake circuit diagnosis and repair.

Using a genuine Kito OEM Rectifier identified by part number ECP93DIAA ensures the replacement component is electrically matched to the EC Series hoist brake circuit voltage and current requirements, physically compatible with the hoist electrical enclosure mounting arrangement, and manufactured to the same performance and reliability specifications as the original part. Replacement must be performed by a qualified hoist technician with electrical competency, and the hoist must be fully inspected, electrically tested, brake tested, function tested, and load tested before returning to service.

Material: Electronic component construction consistent with Kito OEM specifications for EC Series brake circuit rectifiers

Compatible With: Kito EC Series electric chain hoists Part number ECP93DIAA

Uses: Replacement of failed or degraded brake circuit rectifiers in Kito EC Series electric chain hoists Scheduled preventive maintenance and hoist electrical inspection programs Hoist overhaul and electrical refurbishment Restoration of correct electromagnetic brake engagement and release function

Key Features: Genuine Kito OEM replacement rectifier Designed for Kito EC Series electric chain hoists Part number ECP93DIAA AC to DC conversion for electromagnetic brake circuit Ensures correct brake engagement and release throughout hoist operation Matched to EC Series brake circuit voltage and current specifications

Note: Rectifier replacement must be performed by a qualified hoist technician with electrical competency in hoist brake circuit diagnosis and repair. The hoist must be fully inspected, electrically tested, brake tested, function tested, and load tested before returning to service. Never operate an electric chain hoist with a suspected rectifier fault — remove the hoist from service immediately and arrange for inspection and repair by a qualified technician.
