Detcon Model 1010SS-N4X has a built-in 7 amp-hour battery backup circuit designed to provide uninterruptible
24 VDC power (Figure 1). The system includes a 117 VAC/24 VDC power supply that acts as a battery charger.
In operation, 117 VAC (L1, L2 and GND) is connected to a terminal strip to provide power to the power supply.
The 117VAC is also provided as an output via adjacent terminals. The power supply, in turn, keeps the batteries
charged as well as provides 24 VDC to all internal circuits.
The 24 VDC power output rating is 6.25 amps max. Upon loss of 117 VAC power, the 24VDC output is obtained
solely from the internal batteries. In the event that the batteries become depleted, the low voltage cutoff circuit
will disconnect the batteries from the circuit to prevent damage to them. The cutoff voltage is approximately 21
VDC. Once 117 VAC input is restored and the batteries will begin to recharge.
Note that as long as 117 VAC is applied, the 24 VDC output will be available regardless of the charge state of the
batteries.
