Dual Voltage PSU Charger

True 12/24Volt Split Dual Voltage Power Supply Battery Charger solves the problem. Providing both 24Volts and 12Volts in battery standby systems can be inconvenient and costly. By listening to customer feedback Omniflex have introduced the DUAL Voltage PTL Charger series which is a combined power supply and true 12/24Volt Split Battery Charger. Today's RTU's are surrounded by more and more instrumentation required to operate at 24Vdc, whilst the radio system still requires 12V for operation. This gives the system designer a dilemma in single charger systems. If you add an extra converter to convert 12 to 24V, then the 24V power will be limited to the power of the converter, which must need to be sized large enough for PEAK load requirements. If you are driving solenoids or power relays, this can result in a large converter which adds a continuous drain on the system, reducing standby time from the batteries, and of course consumes additional cost and space. If you add an extra converter to convert 24V to 12V to drive a radio, you need to be sure that the converter output is rated for the PEAK transmit power required by the radio. Most radios are designed to be operated of battery supplies, and expect a "stiff" supply for optimum RF performance. The choice of the wrong converter for this application presents a risk. The unique PTL120C-D dual voltage charger from Omniflex now reduces cost solves these issues by the provision of true split rail battery charging. The PTL PSU chargers provide BOTH 12 and 24V battery connected load outputs as if you had two battery chargers in the system. This provides 5A peak load capability on both supplies, capable of driving radios at 12V and power loads at 24V without the additional power, cost and space associated with adding an additional voltage converter. This provides balanced charging to both 24Volt and 12Volt batteries even when light 12Volt loads are tapped from the battery pack. When the average 12Volt load is significant compared to the 24Volt load, a separate 12Volt battery is recommended. For either configuration, the Powerterm PTL Charger series is the only charger component required for the system, reducing space and cost. The PTL Dual Voltage PSU Charger is the ideal solution for applications that include RTU’s, dataloggers, remote field instruments and alarm systems where the requirement exists to power both 12Volt equipment (such as radios) and 24Volt instruments.
