SR100HL
100W – AC/DC Power Supply / Battery Charger
The SR100HL range is designed for use as a reliable and stable AC to DC power supply, or float charger for lead-acid batteries. Note that for float charging the output voltage must be set to approximately 15% above the nominal battery voltage models. This is done as the default voltage for the 12V model but must be specified at time of order for all higher voltage models.
Applications
- Security – Access Control
- Industrial Processes Switching Protection
- SCADA
- Radio Repeaters – Remote Sites
Points of Difference
- Ideal for standby float charging of lead-acid batteries
- Constant current limit and Precise voltage control
- Temperature compensation option
- Efficient modern “current mode”
- Relay Alarms Output
- Suitable for parallel operation
- Rugged design and construction for long life and challenging environments
Optional Features
- American Input Voltage 110 VAC ( 88 – 135 VAC)
- Communication Port ( RS232 ASCII – SR485 – MODBUS Serial – SNMP , webpages)
- Digital Input/Outputs: Customizable 3 digital inputs & 1 digital output.
- Mounting: DIN rail , Rack Mount 19″ with V/I meter available, Wall mount
- N+1 redundancy
- Boost Charger
