Green Light Power Switching

GLPS-SWGreen Light Power Switching Panels (MLO) Main Lug Only and (MCB) Main Circuit Breaker w/Standard High-Inrush Relays

The GLPS-SW Power Switching Panels come standard with 20A branch circuit breakers, and accept 208Y/120 or 480Y/277 volt feeds terminating to main lugs provided. An optional back-fed main circuit breaker may also be specified.

Three panel sizes are available, “Small,” “Medium,” and “Large.” The panel size is ordinarily determined according to the number of control circuits specified, ranging from 8 to 42 circuits per panel. Each control circuit is rated for 16A at 100-277V.

The GLPS-SW panels utilize robust 50A relays to handle all types of lighting loads including electronic ballasts, as well as motors up to 2 HP.

As an option, GLPS-SW panels may be equipped with 0-10V fluorescent dimming control substituted in place of some or all switching circuits. Consult Crestron Sales Support Services to specify this option.

The GLPS-SW panels employ field-replaceable lighting control modules, with 10 or 16 control circuits per module, for excellent configurability and service-ability. Each module includes local relay controls and load state indicators for each circuit, plus additional controls and indicators for use during system commissioning.

Individual hinged doors are provided on the front of each GLPS-SW panel for access to the circuit breaker panelboard and the local controls on each module. As an option, the local control access door may be omitted.

As part of a complete Green Light system, GLPS-SW panels connect to an IPAC-GL1 lighting control processor (or other 2- Series control cystem) via the Cresnet control network. An optional GLA-PWS50 (or equivalent) power supply is also recommended for each panel to provide backup power to the lighting modules.

Remote emergency override mode allows the lighting system program to be overridden while each circuit is set to an override preset state. The override preset for each circuit is set using the local controls on the front of each lighting module. Remote override mode is activated by an external contact closure from a Crestron GLS-PLS-120/277 power loss sensor or other devices.

All low-voltage connections to a GLPS-SW panel are made via a connector block located near the bottom of the panel. Connections are provided for Cresnet communications, backup power supply, and emergency override. Crestron Green Light Power Switching panels are configured to order, and factory assembled and tested prior to shipping. Each panel is engineered to provide a clean and manageable installation with abundant provisions for wire termination and conduit knockouts. On-site installation is fast and easy with all termination points clearly labeled and accessible from the front.

MODEL NUMBERS

Specifying and ordering a Crestron Green Light Power Switching panel is facilitated using the following model number system. Simply fill in the appropriate entry in each position according to the steps that follow:

GLPS - SW - MLO - 30 - 120 - 10K – ND

GLPS-Relay Type-Feed Type-Number of Ckts-Voltage-AIC Rating-Door Option

The above example is for a “Main Lug Only” panel with 30 “SW” standard high-inrush relays, 120V / 10kAIC circuit breakers, and no local control access door.

Relay Type: Enter “SW” to specify standard high-inrush switching relays.

Note: For other relay types, refer to the Selection Guide

0-10V fluorescent dimming is also available. Consult Crestron Sales Support Services to specify this option.
