MAXIFLEX SLC Power Supply Module Model M1101A – Solar Powered or 24Vdc + Battery Charger Logic Power Module. DATASHEET FEATURES • Operate MAXIFLEX systems from Solar Power Fits in PSU Slot of MAXIFLEX Base Up to 24 hours stand-by time. Contains integral +12Vdc Battery Charger Temperature Compensated Battery Charger for operation in extreme temperatures conditions. Includes +12Vdc Field Supply for powering I/O etc. Power Supply Monitoring for reliable system operation CE certified for international application. The M1101A Power Supply Module (SLC PSU) is powered from a Solar Panel or an external +24Vdc (nominal) supply, and provides the primary logic and field power for a MAXIFLEX I/O Base. This power module also incorporates a +12Vdc field supply for powering I/O, radios etc. and a battery charger suitable for sealed lead acid (SLA) batteries. This power supply module is intended for use in MAXIFLEX systems where power is not available locally, and solar panels must be used to power the system. An optional 24Vdc input is provided for alternate power sources should these be available. The integral battery charger is temperature compensated to provide optimum capacity from the connected Sealed Lead Acid (SLA) Battery over the full temperature range using an external sensor. An integrated battery voltage monitor is provided which allows the MAXIFLEX CPU in the system to monitor the current battery voltage, and status of the incoming supply for full RTU status monitoring. A battery low voltage cut-out is provided to prevent batteries from entering their deep-discharge state when the battery is depleted. Up to 24 hours standby can be achieved with a 24Ah SLA battery in small systems (dependent upon the number I/O Modules).
