Model C2195A PTS Powerterm Solar Regulator - 1

PTS PSU/Charger Model C2195A 6Amp Solar Regulator/Power Supply • A Complete solution for small solar powered instrument power systems. • Works with 12V or 24V Solar panels. • Ideal for Teleterm M2 RTU’s, dataloggers, remote field instrumentation, alarm systems, remote access systems etc. • Digital output to indicate charging Charging characterised for sealed lead-acid cells. 12Vdc or 24Vdc operation. Operates with up to 140W Solar Panels Under-voltage cut-out protects battery from deep discharge. Overview The Powerterm PTS is a combined Solar Regulator and Power Supply system with integrated standby battery management for small solar powered applications. Just connect a solar panel, sealed lead acid battery and load for an industrial grade solar powered system. This DIN rail mounted product is ideal for providing dc power to Teleterm M2-series RTU systems when mains power is not available. Applications include RTU’s, dataloggers, remote monitoring, and alarm systems. Under-voltage Cut-Out In the event of complete discharge of the battery, an under-voltage cut-out disconnects the load preventing the battery entering its “deep” discharge phase, which can cause irreparable damage to the battery, and reduce its capacity and life. Fault Protection Batteries are capable of delivering very large currents under system fault conditions that can damage wiring and equipment. The PTS incorporates an auto-resettable Series regulator design for best efficiency. Solar charging output for system monitoring. DIN Rail mounting Temperature compensated battery charging for best standby time and battery life. load cut-out, which disconnects the load under overcurrent fault condition. Charge Control The PTS controls the charging of the battery to ensure optimum life. When the battery is fully charged, the PTS will disconnect the solar panel to prevent overcharging. System Monitoring The PTS provides a Charge detect output. When the solar panel is connected and charging, this output is on. This output can be used to detect solar panel or charger failure, or to measure actual charging hours. 12/24V Selectable The PTS can be used in 12V or 24V applications. The PTS can be switched to the correct battery voltage and adjusts the solar regulator and low voltage cut-out accordingly. Temperature Compensation In outdoor environments, the ideal battery voltage will vary with temperature. The PTS has a temperature sensor that compensates for changes in ambient temperature to keep the battery at its optimum. Copyright Omniflex ♦ Subject to change without notice

PTS PSU/Charger Model C2195A 6Amp Solar Regulator/Power Supply APPLICATION NOTES SOLAR PANELS SOLAR PANEL MOUNTING Solar panels are usually classified by their rated power output in Watts, determined by multiplying rated voltage by rated current. This rating is the amount of power the solar panel would be expected to produce in peak sunlight conditions. The optimum angle to mount a solar panel is to point the panel exactly due “solar” north or “solar” south (depending upon your hemisphere) at an angle from vertical equal to your latitude + 10 to 15 degrees. “Solar” north or south can easily...

Model C2195A PTS Powerterm Solar Regulator - 5

PTS PSU/Charger Model C2195A 6Amp Solar Regulator/Power Supply CHARGE DETECT OUTPUT A logic output across terminals 7 and 8 is provided to detect the presence/absence of solar charging. A High output (output on) confirms that the Solar Panel voltage is above the battery voltage, and that charge current is going into the battery from the solar panel. The output load could still be greater than this current in off-peak sun conditions, and so this does not always indicate net positive charging of the battery. A green light labelled ‘CH’ on the front of the PTS is a visual indication of the...
