Description
SR250HL – 250W
Standalone DC Power Supply / Battery Charger
The SR250HL 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
