RELIANCE ELECTRIC 14C109U S/N:1GN026299 FlexPak Plus Non-Regenerative DC Drive

Overview

The RELIANCE ELECTRIC 14C109U S/N:1GN026299 is a FlexPak Plus series non-regenerative DC drive from Reliance Electric, rated 5HP, 230VAC single phase input. The RELIANCE ELECTRIC 14C109U S/N:1GN026299 is designed for armature voltage or tachometer feedback closed-loop speed control of shunt-wound DC motors. It accepts analog speed reference signals and delivers stable adjustable armature output for constant speed applications without four-quadrant regeneration. The RELIANCE ELECTRIC 14C109U S/N:1GN026299 is a legacy discontinued unit and is stocked for maintenance and emergency replacement of existing FlexPak Plus DC motor control systems.

Features

The RELIANCE ELECTRIC 14C109U S/N:1GN026299 supports armature voltage feedback as standard, with optional tachometer feedback kit for tighter speed regulation. It integrates built-in protection functions including overcurrent, field loss, phase fault, and overtemperature shutdown. The RELIANCE ELECTRIC 14C109U S/N:1GN026299 provides configurable analog reference input and auxiliary relay fault outputs for machine interlock. It can be fitted with optional dynamic braking accessory for faster stopping. The RELIANCE ELECTRIC 14C109U S/N:1GN026299 uses fan cooling and shares the same mechanical footprint and wiring layout as the 14C109 base model.

Specs

Device Type: Non-regenerative DC drive Model: RELIANCE ELECTRIC 14C109U S/N:1GN026299Series: FlexPak Plus Rating: 5 HP, 230 VAC, single phase Max Armature Current: 35 A Control Type: Non-regenerative thyristor armature control Feedback: Armature voltage feedback (standard), tachometer feedback optional Protection: Overcurrent, field loss, phase loss, overtemperature Accessories: Optional dynamic braking kit, tachometer feedback kit Mounting: Cabinet rack mounting Status: Discontinued legacy drive Serial Number: 1GN026299

Principle

The RELIANCE ELECTRIC 14C109U S/N:1GN026299 receives speed reference signal from the host controller or potentiometer. The thyristor power bridge adjusts the average armature voltage to regulate DC motor speed. The control board continuously samples armature voltage or tachometer pulse to correct speed deviation. Unlike regenerative versions, this unit cannot return braking energy back to the AC line; stopping energy is dissipated via optional dynamic brake resistor. When fault conditions are detected, the RELIANCE ELECTRIC 14C109U S/N:1GN026299 blocks firing pulses and activates fault relay output.

Applications

The RELIANCE ELECTRIC 14C109U S/N:1GN026299 is used for constant speed DC motor control on conveyors, mixers and extruder auxiliary drives. It serves test bench and material handling equipment DC motor speed regulation. The RELIANCE ELECTRIC 14C109U S/N:1GN026299 applies to spare replacement and troubleshooting of existing FlexPak Plus non-regenerative DC drive installations. It also supports retrofit for older printing and processing machinery.
