Powerbox Rolls Out New 1200W AC-DC Power Supply

The OFI1200A is available in three versions of single output DC voltage, 12V/84A; 28V/43A and 48V/25A. Using a high-efficiency topology, the typical efficiency for the 48V output unit at 230VAC input is an excellent 92%.

Powerbox has released 1200W rated OFI1200A AC/DC power supply for industrial applications.

Powerbox Power SupplyOptimized for conduction cooling, the OFI1200A delivers high-performance levels across a baseplate temperature range of -40 to +95 degrees C without the use of a fan.

Conduction cooling requires very specific building practices and the PRBX OFI1200A has been designed to guarantee optimal heat transfer from the dissipating components to the baseplate, delivering a high level of performance within an operating temperature of -40 to +95 degrees centigrade at the baseplate.

Depending on the assembly method and the overall cooling conditions, a derating may apply as specified in the technical documentation.

To cover a large range of applications, the OFI1200A operates with a wide universal input range from 85 to 305VAC (Nominal 100 to 277VAC). The unit includes a PFC with a coefficient of 0.98/0.95 (110VAC/230VAC).

The OFI1200A is available in three versions of single output DC voltage, 12V/84A; 28V/43A and 48V/25A. Using a high-efficiency topology, the typical efficiency for the 48V output unit at 230VAC input is an excellent 92%.

To make it possible for customers to precisely adjust the voltage and current to their application, the OFI1200A offers two analog inputs, VTRM and ITRM.

The extended trimming and control function simplifies the utilization of the power supply in constant voltage (CV) or constant current (CC) mode, without adding external circuitry.

For safety, the OFI1200A has an IN/OUT isolation of 3,000VAC and IN/FG of 2,000VAC. Output isolation to FG is 500VAC. The power supply includes overcurrent protection with auto-recovery, over-voltage and over-temperature protection.

The OFI1200A board includes easy access to auxiliary functions via onboard connectors, namely: Remote Control, Output Voltage Sensing, Power Good, VTRM, ITRM.

The OFI1200A has passed shock and vibration testing as specified in MIL-STD-810H.

In that respect, the products have been tested to levels far above normal operating conditions and are designed to sustain high, 20G level shocks.

In its open frame format, the OFI1200A measures 142 x 39 x 260mm (5.59 x 1.54 x 10.36 inches) and weighs 1.2kg max.

An optional metal cover is available, adding just 1mm to the height and 200 grams to the weight (Option-N).
