POWER-AC2PNDC-15A/B.  24VAC to Low Current Dual Output 15 & -15 Voltage DC power supply board/Regulator Interface board.

 

the POWER-AC2PNDC-15A/B are an Electronics board that allows you to connect Low voltage 24VAC or 17 to 32VAC on one side of the board (AC1 & AC2)and get dual low current regulated voltages, 15VDC and -15VDC  on the other side (+V & -V corresponding). Every industrial application designer should have a few of these boards handy. The boards will allow you to easily power all your Industrial Op-Amp transducers. The Terminal Block TB connector is included and makes it easy to use. 

 

The POWER-AC2PNDC-15A/B. board is designed to convert low current 24 VAC to stabilize +/- 15V DC. If used properly, it will eliminate the need for expensive industrial power supplies, which would otherwise be needed to carry out the same task.

 

AC3PNDC-15A/B is easy to install, setup and operate. If you want to  professionally power your HVAC products, POWER-AC2PNDC-15A/B offers the features you need. Mounted easily via tow 0.125" mounting holes.

 

The board is designed to attenuate, filter and regulate low current low voltage AC to stable +/-15V DC.

Basic operation of the voltage regulator board

 

The half diodes bridge D1-D2, together with the capacitor C1, C3 will convert input 24VAC voltages to dual DC voltages.

 

The other side of the diodes bridge drives the low current voltage regulators U1 and U2. The voltage regulators are the main component of this regulators. The POWER-AC2PNDC-15A/B board typically has the ability to drive currents up to 80mA. For maximum voltage regulation, adding capacitors C2 and C4 correspondingly in parallel between the common leg and the output. This eliminates any high frequency AC voltage that could otherwise combine with the output voltage.
