ELK-TRG1640 16.5VAC 45VA Alarm Transformer

Reliable AC power for a compatible alarm control panel. The ELK-TRG1640 is a professional-grade plug-in transformer with a 16.5 VAC, 45 VA output. It can be an excellent replacement for an aging or failed alarm transformer when the panel's installation instructions call for 16.5 VAC and permit a 45 VA supply. That may include selected Honeywell/Resideo, DSC and GE/Interlogix systems; compatibility depends on the exact control-panel model, not the brand name alone.

Why choose the ELK-TRG1640?

• 45 VA capacity: supports equipment designed for this output rating; verify the panel's specified transformer size and input requirements.
• Auto-resetting PTC-protected secondary: built-in output protection helps the transformer recover after an overload is corrected.
• Green power-on LED: provides a quick indication that AC input power is present at the transformer.
• Grounded plug and terminal: supports the grounding arrangement specified by ELK and the equipment instructions.
• Outlet mounting tab and wire strain relief: help secure the plug-in unit and low-voltage wiring at the receptacle.
• UL listed, Efficiency Level VI: manufacturer-listed features for this model.
• ELK limited lifetime warranty: subject to the manufacturer's terms and authorized-sales requirements.

Technical specifications

Check compatibility before replacing your transformer

Read the transformer rating in your alarm panel's installation manual and check the existing transformer label. Match the required AC voltage, verify that the 45 VA rating is permitted, and follow the panel manufacturer's grounding, receptacle and wiring instructions. Do not use this 16.5 VAC transformer on a panel that requires 12 VDC, 18 VAC, 24 VAC or a different specified power source. The TRG1640 supplies AC power; it is not a regulated DC supply or a standby battery.

If a panel reports AC loss, a new transformer may not solve the underlying problem. The receptacle, wiring, breaker, panel input and battery-charging circuit may also need testing. Disconnecting power to a monitored alarm can create a trouble signal or interrupt protection. Have a qualified alarm technician evaluate and test the system after replacement.
