SHORT DESCRIPTION

The LAD-120 series AC/DC power supplies with UPS function are cost-effective, low profile. It is the perfect solution for security systems where uninterruptible power supply is required. The power supply can be supplied with voltages from 90VAC to 264VAC. Versions are available with output voltages of 13.3V, 27.6V, 41.5V and 55.2VDC.The power supply has a high efficiency of 88% and has integrated mains voltage and battery switches for ease of system maintenance. The LAD-120 series power supplies have TTL signals for system monitoring: AC OK, battery disconnected, battery reversed (no damage to the system), battery discharged, battery fully charged, battery discharged. These signals make it easy to integrate the LAD series power supply into any security or fire protection system.

BLOCK SCHEME

MAXIMUM LOAD DEPENDING ON AMBIENT TEMPERATURE

MAX POWER DEPENDING ON THE SUPPLY VOLTAGE LEVEL

1. DC-UPS FUNCTION

When the mains voltage becomes abnormal, the UPS function is activated and the connected devices are powered by the battery

2. OBTAINING FUNCTIONAL SIGNALS USING TTL

Functional signals are sent via connector CN2.

An external power supply is required to receive TTL signals. Maximum voltage 50VDC, maximum current in the circuit 30mA.

2.1 AC OK: MAINS VOLTAGE STATUS

2.2 BATTERY STATUS: DISCONNECTED/CONNECTED WITH INCORRECT POLARITY

2.3 DISCHARGED BATTERIES

2.4 FULLY CHARGED BATTERY

2.5 DISCHARGING THE BATTERY

2.6 FORCED ACTIVATION OF UPS MODE
