VxI Power, a U.K. based manufacturer of battery backed power supply solutions, stated that it has expanded its Oracle (News - Alert) family of battery-backed SWITCH-mode power supplies with the addition of a new 200W model that features a built-in RS232/RS485 interface and full Modbus functionality, making it particularly suitable for use in telemetry applications.  

According to the company, the latest additions to the growing Oracle range are the feature rich 200W units. Available in a wide range of output configurations, the range offers optimum flexibility and incorporates VxI Power’s intelligent battery charging technology. “Klippon” quick release input and output connectors are fitted as standard, but these also can be user specified. 

These features continue the philosophy of the Oracle series - customer led design offering maximum functionality to give minimum downtime. Built-in protection circuitry guards against: short circuit overloads, current limits, reverse polarity, over & under voltages, battery disconnection and low battery conditions.    

LEDs are provided for local monitoring of system status, along with the options of RS232/RS485, Canbusand Devicenet communications. The serial port is designed to connect directly to other hardware for incorporation into a SCADA System or can be used to download data to a pc or similar device. LEDs and fault relays can be mapped to a number of fault and status conditions.

Operating from an 85-264VAC auto-ranging input, the Oracle III 200e provides one regulated main output, one battery-charging output and an optional auxiliary output. The main output is derived from the PSU during normal operation, and an internal diode automatically switches to battery power in the event of mains failure. 

Available in 12V and 24V versions, the new PSU is equipped with either Klippon or IEC (News - Alert) inputs or an external heat-sink, which enables it to achieve a peak output power of 300W or to operate in ambient temperatures up to 70C without the need for an internal fan. 

The on-board Modbus capability means that users can remotely monitor parameters such as system load or battery state and even remotely initiate a battery test cycle. 

The company asserted that the Oracle III 200e is available in a variety of case styles, including panel-mount, chassis-mount, DIN-Rail mount and Eurocard module acquiescent with the BS EN 61000-6-3 and BS EN 61000-6-2 standards for EMC (News - Alert) emissions and immunity.
