POWER-AC3PNDC-15LD.  Low Current Dual Output 15 & -15 Voltage DC power supply board/Regulator Interface board with step-down power transformer (110V/60HZ primary).


the POWER-AC3PNDC-15LD. is an Electronics board that allows you to connect 110VAC/60HZ on one side of the board and get dual low current regulated voltages, 15VDC and -15VDC  on the other side. 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-AC3PNDC-15LD. board is designed to convert low current high voltages AC 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-15LD is easy to install, setup and operate. If you want to  professionally power your HVAC products, POWER-AC3PNDC-15LD 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.

Commonly utilized as the heart of DC Power Supply for Amplified and In-Line Amplified Transducer.


Basic operation of the voltage regulator board


Form the 110V AC the voltage drops to low dual AC voltages through the step down power transformer, the full diodes bridge D1-D4, together with the capacitor C1, C3 will convert input dual AC 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-AC3PNDC-15C 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.
