Batteries must be ordered separatly.

EL500-4803 has been specifically developed to meet the DC powering requirements for telecommunications, industrial and marine applications. The unit has a 230Vac, power factor corrected single phase input with soft-start, and operates over a wide range of input voltage. The output is current limited, with short circuit protection. EL500-4803 is a high quality and reliable switch mode power supply with low weight, small mechanical dimensions and high efficiency. It is designed to work in parallel with a 48V battery, giving a no-break power supply for different electronic equipments such as fire alarm systems, intruder alarm, access control systems aso. EL500-4803 has relay contacts output (potential free) giving information about battery condition, mains and charger failure. Light emitting diodes indicates battery condition, mains/charger "OK", overload and fuse errors.

• Output power 166W (55,2V/3A)
• 2 output circuits with fuses and LED’s which illuminates by fuse break. 
• All outputs are secured against overload, short circuit and over voltage.
• Potential free alarm output for main/charger fault.
• Potential free alarm output for battery failure.
• Separate input for battery connection to achieve a "No-Break distribution system"
• Built in battery test function, controlled automatically or externally.
• Automatic protection against deep discharging of the battery.
• Approved by NEMKO and marked with CE label.
