The ZDSO500-DR power supplies are dedicated to operate with voice alarm systems (VAS). They act as battery charger and supervision system for external batteries for backup voltage 24 V, according to the EN 54-4 + A1 + A2 standard.
Features
- dependence of floating operation and bulk charging voltages on temperature
- battery charging with current limitation
- low & high battery voltage control
- battery circuit continuity control and measurement of its resistance
- battery protection against too deep discharge
- automatic voltage equalization between batteries
- internal temperature control
- optical and remote signalling of failures
Equipment
- set of four signalling LEDs
- error reset button
- Ethernet communication connector on the rear panel (optional)
- internal deep discharge disconnector of battery
- slide switch for selecting the battery capacity and resistance of the battery circuits
- remote signalling terminals with NO and NC contacts: collective, battery and mains failure
- external fault input connector (active when open) referred to the negative common rail of the power supply
- two external temperature probe connectors for measuring the temperature of battery bank and ambient temperature (probes included)
- IEC C14 socket for connecting the power supply
- internal electronically switched fan
- USB connector for service purposes (diagnostics, calibration, software update)
