RELIANCE ELECTRIC 14C1090 S/N:1GNO26299 FlexPak Plus DC Regenerative Drive

Overview

The RELIANCE ELECTRIC 14C1090 S/N:1GNO26299 is a FlexPak Plus series regenerative DC drive from Reliance Electric, designed for DC armature motor speed and torque control. The RELIANCE ELECTRIC 14C1090 S/N:1GNO26299 supports four-quadrant regenerative operation to return braking energy back to the AC line, ideal for overhauling loads such as unwinders, winders and hoists. It accepts analog command signals and provides adjustable current, speed and ramp settings for closed-loop DC motor regulation. The RELIANCE ELECTRIC 14C1090 S/N:1GNO26299 is a legacy discontinued unit and is stocked for maintenance and emergency repair of existing Reliance FlexPak Plus systems.

Features

The RELIANCE ELECTRIC 14C1090 S/N:1GNO26299 features regenerative bridge design for 4-quadrant operation and energy regeneration during motor braking. It supports armature voltage feedback and tachometer feedback for stable speed regulation. The RELIANCE ELECTRIC 14C1090 S/N:1GNO26299 integrates comprehensive protection including overcurrent, field loss, overvoltage and overtemperature alarms. It provides configurable analog and digital I/O for enable, fault output and speed reference connection. The RELIANCE ELECTRIC 14C1090 S/N:1GNO26299 uses cabinet fan cooling and matches the original FlexPak Plus mounting footprint.

Specs

Device Type: FlexPak Plus regenerative DC drive Model: RELIANCE ELECTRIC 14C1090 S/N:1GNO26299Series: FlexPak Plus Control Type: Four-quadrant regenerative DC armature control Feedback Options: Tachometer feedback, armature voltage feedback Command Input: Analog ±10V speed reference Protection: Overcurrent, field loss, overvoltage, overtemperature, phase fault Cooling: Forced fan cooling Enclosure: Cabinet mount Status: Discontinued by manufacturer Serial Number: 1GNO26299

Principle

The RELIANCE ELECTRIC 14C1090 S/N:1GNO26299 receives speed reference signal from the control system. The thyristor power bridge adjusts armature voltage and current to drive the DC motor. When the motor runs in overhauling mode, the drive reverses power flow and feeds regenerative energy back to the AC supply. The control board continuously samples tachometer and armature signals to maintain closed-loop speed. When fault conditions are detected, the RELIANCE ELECTRIC 14C1090 S/N:1GNO26299 blocks firing pulses and triggers fault indication.

Applications

The RELIANCE ELECTRIC 14C1090 S/N:1GNO26299 is used for winder and unwinder control in extrusion, film and textile lines. It serves hoist, crane and elevator DC motor drives with overhauling load. The RELIANCE ELECTRIC 14C1090 S/N:1GNO26299 applies to spare replacement and troubleshooting of legacy Reliance FlexPak Plus DC drive systems. It also supports test bench and metal processing equipment DC motor control.
