ETPS - DC Power Supply

Features: 

  • Low Cost, Small Size. 

  • Current Limit Protection. 

  • Full and Half-Wave rectifiers. 

  • Fixed and Adjustable Voltage. 

Application:

The ETPS can be used as an inexpensive DC power supply in applications where a cost effective local power source is required.

The board may be used to provide excitation to auxiliary control equipment and/or sensors. 

Product Description:

The ETPS board contains a simple linear power supply that can be adjusted for the most common DC voltages (up to 24 VDC) used in HVAC control industry. A precision trim pot is included on board for field voltage adjustments.

The board's rectifier can be half-wave (a diode) or full-wave (a bridge) depending on the equipment grounding requirements.  The ETPS delivers 5 to 24 VDC with a current rating depending on the output voltage and type of rectifier used. The board includes a 2A glass fuse in the AC supply circuit.

The board is equipped with angular connectors for fast and easy wiring and mounts in a 2.75" wide snap-track (provided). 

Specifications:

Power: 24 VAC from control transformer.
Output: Adjustable DC voltage from 5 to 24 VDC. Full wave and half wave rectifier available. Max. load voltage dependent (i.e 1.0 A @ 24 VDC and 0.5 A @ 12 VDC).  See table on wiring diagram for more details.
Indication: Power Output - green LED. 
Dimensions: 1.0" x 2.75 “ (25 x 70 mm) , board mounts in TR-2 snap-track (provided).
