PRESS RELEASE - 18th JANUARY 2005
New 200W
battery-backed PSU offers multiple outputs
for
greater design flexibility

The new Oracle III 200-9
battery-backed switch-mode power supply from VxI Power offers designers greater
flexibility by providing one main output, one charger output and up to seven 35W
auxiliary outputs.
Operating from an
85-264V AC autoranging input, the PSU is available in both 12V and 24V versions
and features fan cooling as standard, enabling it to deliver 200W continuously
at the maximum permissible ambient temperature of 70degC, with a peak output
capability of 300W.
In the event of a mains
failure, the backup battery supplies power to the load via an
internal diode, thereby ensuring that the output is maintained without
interruption.
Temperature compensation
of the battery charger circuit extends all the way down to the minimum operating
temperature of –20degC, and a special version of the PSU with a lower limit of
–40degC is also available for extreme applications.
The unit is capable of
charging ‘Cyclon’ cells over the full temperature range and can also be
configured for either 2- or 3-stage charging to reduce battery recharge times in
cyclic applications.
The 200-9 features the
standard Oracle III RS232/RS485 serial communications interface, with a choice
of Modbus, Canbus, DeviceNet or IrDa protocols. As well as enabling data to be
downloaded to a PC, this facility makes it possible for users to input
parameters such as battery type and battery test interval. In addition, the serial interface allows
the PSU to be integrated into a SCADA system, if
required.
Built-in protection
circuitry guards against short-circuit overloads, current limits, reverse
polarity and overvoltages, while an undervoltage lockout facility prevents
damage to the battery when it is fully discharged.
The PSU incorporates
volt-free relays and LEDs for monitoring system status, and these can be
factory-configured to meet the user’s specific
requirements.
Compliant with the
EN50081-1 and EN50082-2 standards for EMI emissions and immunity, the Oracle III
200-9 has overall dimensions of 203 x 185 x 70 mm.
