Crestron CLX-1DIMU4-HP – 4-Channel High Power Universal Dimmer Module, 1 Feed, 120V

Product Overview

The Crestron CLX-1DIMU4-HP is a high-power 4-channel universal dimmer module designed for installation in Crestron CAEN or CAEN-MLO automation enclosures. It accepts a single 120 VAC feed and delivers 10A / 1,200W per channel, supporting a broad range of dimmable load types including LED, incandescent, electronic low-voltage (ELV), and magnetic low-voltage (MLV). Its high per-channel capacity makes it appropriate for architectural lighting systems with significant load requirements.

Product Description

The CLX-1DIMU4-HP occupies one module slot in a CAEN or CAEN-MLO enclosure and communicates via Cresnet for control from a Crestron processor. Unlike standard CLX dimmer modules, the HP variant provides 10A per channel (versus 5A standard) and supports a minimum load of 0W, accommodating installations where channel counts vary widely. Wire gauges from 14 to 10 AWG are accepted per load terminal. Heat dissipation starts at 8.5 BTU/hr base with additional dissipation per amp of load current, reaching a maximum of 121 BTU/hr at full load.

Frequently Asked Questions

Q: How does the CLX-1DIMU4-HP differ from the standard CLX dimmer modules?
A: The HP (High Power) variant provides 10A / 1,200W per channel versus the standard 5A / 600W, and supports a 0W minimum load. This makes it suitable for high-wattage circuits where standard modules would be undersized.

Q: Does the CLX-1DIMU4-HP require a specific CAEN enclosure?
A: The CLX-1DIMU4-HP fits any standard Crestron CAEN or CAEN-MLO enclosure that accepts CLX-Series modules. It occupies one module slot.

Q: Is the CLX-1DIMU4-HP compatible with 0-10V dimming or DALI fixtures?
A: No. The CLX-1DIMU4-HP uses phase-cut dimming (forward/reverse). For 0-10V dimming control, the CLX-2DIMFLV8 is the appropriate module.
