Backup power supply (APS-1412)

APS-1412 is a switch-mode backup power supply for devices requiring 12 V DC, included in the alarm system or other installations.

The power supply is characterized by a high output current of 14 A, which determines the maximum current delivered by the power supply connected to the load. When the battery is being charged, this value is reduced by the maximum battery charging current: 12 A (powering devices) + 2 A (charging battery). Energy efficiency of the APS-1412 power supply is up to 92%.

The system complies with EN 55011 Class B in terms of the level of conducted and radiated EMI. It also meets the requirements of EN50131-3 Grade 2 standard as well as EN 60950-1 safety standard.

Indisputable advantages of its structure include: a built-in interference suppression filter and an active system for power factor correction (PFC) - up to 0.99. This ensures very good and stable operating parameters, also in the presence of high fluctuations in the supply voltage.

Lead-acid batteries or other battery types with similar charging characteristics can be connected to the device. This enables uninterrupted operation of the system to be maintained - even for several hours - when the primary power source fails.

Additionally, APS-1412 comes with:

• battery charge status control (including internal resistance measurement)
• battery deep discharge protection.

The power supply is provided with 4 OC type fault signaling outputs. The LEDs located on the anodized aluminum enclosure indicate:

• power output status
• battery status
• AC status
• too high temperature of the power supply.

Audible signaling of troubles is also available.

The system is provided with over-current and short-circuit protection. The power cable is connected to the IEC C14 connector.
