10 AMP SUPERVISED POWER SUPPLY/CHARGER P3PS-10-SU PRODUCT SPECIFICATION DESCRIPTION The P3PS-10-SU is a supervised power limited supply / charger that switches the AC input, into a 12VDC or 24VDC power limited output, with 10 amps of continuous supply current (see Features). FEATURES 110VAC ~ 120VAC input. 12VDC or 24VDC selectable output. Maximum charge current 0.5 amps. 10 amps continuous supply current at 12VDC-24VDC. Filtered and electronically regulated outputs. Built-in charger for sealed lead acid or gel type batteries. Automatic switch over to stand-by battery when AC fails (70% voltage drop at input). AC input and DC output LED indicators. AC fail supervision (form "C" contacts). Low battery supervision (form "C" contacts). Short circuit and thermal overload protection. Includes battery leads. Fans are controlled by thermo-sensor to help dissipate heat.* Board Dimensions: 179.3mm(L) x 108.7mm(W) x 56mm(H) *Specified at 25°C ambient.

Mount the P3PS-10-SU in an optimal location. 2. Before connecting the input power, select the P3PS-10-SU desired DC output voltage (12VDC or 24VDC) via SW1 (see Voltage Output/Transformer Selection Table). 3. Connect AC power 120VAC and 60Hz to terminals marked [N AC L] Use 18 AWG or larger for all power connections (Battery, AC input, DC output). Use 22 AWG to 18 AWG for power limited circuits (AC Fail/ Low Battery reporting). 4. Connect devices to be powered to terminals marked [+ DC -]. Note: It is important to measure output voltage before connecting devices. This helps avoid potential damage. 5. When the use of stand-by batteries is desired, they must be sealed lead acid or gel type. Observing polarity connect battery to terminals marked [+ BAT -] on the board (battery leads included). Use two (2) 12VDC batteries connected in series for 24VDC operation. Note: When batteries are not used, a loss of AC will result in the loss of output voltage. 6. Connect appropriate signaling notification devices to AC Fail & Low battery supervisory relay outputs marked [N.C., C, N. O.] 7. All power must be removed when installing the fan. In order to dissipate heat, the circuit board must be mounted close to the fan, and the fan must be installed relative to the ventilation holes in the enclosure. The ventilation holes cannot be obstructed in any way. P32008-09/11
