Product Details

The Functional Devices TR20VA003 is a 20 VA isolation transformer designed for building automation, HVAC, and temperature control systems. It features a 24 VAC primary input and 24 VAC secondary output, making it ideal for isolating and powering 24-volt control circuits in commercial and industrial environments.

Key Features:

  • VA Rating: 20 VA
  • Primary Voltage: 24 VAC
  • Secondary Voltage: 24 VAC
  • Frequency: 50/60 Hz
  • Mounting: Foot mount and single 1/2" NPT threaded hub mount
  • Over Current Protection: Inherently limited
  • Construction: Split-bobbin design
  • Wire Length: 8.0" leads with 0.5" strip
  • Operating Temperature: -30°F to 140°F
  • MTBF: 100,000 hours at 77°F
  • Approvals: cULus Listed (US & Canada), CE, RoHS compliant

Part of the Functional Devices RIB TR Series, this transformer offers flexible installation with dual mounting options — foot mount or single threaded hub — and is inherently limited for built-in overcurrent protection without a separate circuit breaker. The split-bobbin construction provides reliable electrical isolation between the primary and secondary windings.

Well-suited for use in building automation systems, energy management systems, and HVAC control panels where a dedicated 24 VAC isolation transformer is required.

Great price and delivery time on live well timer order. Other order of boat trailer guidepost kept getting cancelled so placed call to boatplicity to find out they do not sell that part. An email to me explaining why order was cancelled would have been nice. Otherwise all good.

Qwick service
