POWERBOX

OFI1200A


Description

Powerbox, one of Europe's leading power supply specialists and leader for more than 40 years in optimizing power supply solutions for the most demanding applications, announces the release of a new 1200W power supply for industrial applications , model OFI1200A AC/DC. Optimized for conduction cooling, the OFI1200A power supply delivers high levels of performance over a base temperature range of -40 to +95°C, fanless. The power supply works with a wide universal input range from 85 to 305 V AC with power factor correction (PFC). Intended for a wide range of applications, it benefits from an adjustable output voltage and current between a value close to zero and the maximum value authorized for each model.


Technical details

A number of industrial applications require power supplies that operate with limited cooling or no ventilation. In this regard, these include devices operating in aggressive environments where electronic equipment is installed in a waterproof enclosure, radio communication systems exposed to adverse weather conditions, display systems and signaling devices traffic, and interior fittings with stringent restrictions on audible noise. In addition to environmental requirements, reliability and maintenance issues lead system designers to avoid using fans and blowers.

Conduction cooling requires very specific manufacturing practices. Thus, the PRBX OFI1200A model has been designed to guarantee optimal heat transfer from the dissipation components to the base, which makes it possible to obtain a very high level of performance in a temperature range between -40 and +95°C at base level. Depending on the assembly method and the overall cooling conditions, power reduction is possible, according to the technical documentation.

To meet a wide range of applications, the OFI1200A power supply operates with a wide and universal input voltage range of 85 to 305 VAC (100 to 277 VAC nominal). This unit has a power factor corrector (PFC) with a coefficient of 0.98/0.95 (110 V AC/230 V AC).

The OFI1200A model is available with three DC output voltages (12 V/84 A, 28 V/43 A and 48 V/25 A). Thanks to a highly efficient topology, the characteristic efficiency of a unit offering a 48 V output for an input voltage of 230 V AC reaches an excellent value of 92%.

Industrial applications, especially professional lighting or low-power electrolysers, require the power supply to deliver a constant current, which must be easily adjustable. Often, this equipment operates in environments that require the electronics to be housed in an enclosure and protected from harm. This requires the power supply to offer an external command to adjust the output voltage and/or current between the maximum allowed value and near zero.

To allow customers to fine-tune voltage and current to suit their application, the OFI1200A power supply offers two analog inputs, VTRM and ITRM. With these functions, it is possible to adjust the output voltage and current from almost zero voltage to a maximum voltage specified by model. For example, the 28V output is adjustable from nearly zero volts to 33.6V, and the output current from nearly zero amps to 43A. output using the built-in potentiometer.

Extensive control and trimming functionality simplifies the use of the power supply in constant voltage (CV) or constant current (CC) mode, without adding external circuitry.

For applications that require redundancy or greater power, up to nine units can be connected in parallel, delivering an exceptional total power of up to 9720 W in conduction cooling mode. To maintain maximum efficiency with parallel or redundant operation, the optional active logical-OR circuit with high-performance FET technology (Option-O) is available on the OFI1200A28 and OFI1200A48.

Regarding safety, the OFI1200A power supply has IN/OUT isolation of 3000 V AC and IN/FG of 2000 V AC. The output - FG isolation is 500 V AC. The power supply includes overcurrent protection with automatic recovery, as well as overvoltage and overtemperature protection.

The OFI1200A power supply board provides easy access to auxiliary functions through connectors mounted on the board, namely: Remote control, Output voltage detection, Power Good, VTRM, ITRM.

The OFI1200A power supply has successfully passed shock and vibration tests to MIL-STD-810H. In this regard, the products have been tested at levels well above normal operating conditions and are designed to withstand vibration levels of 20G.

In its form without enclosure, the OFI1200A power supply measures 142 x 39 x 260 mm (5.59 x 1.54 x 10.36 inches) and weighs 1.2 kg max. A metal cover is offered as an option, for barely 1 mm more in height and 200 grams more in weight (option N).

With a design optimized for conduction cooling, the OFI1200A is suitable for applications that require a quiet power solution, such as control rooms. Likewise, the product is suitable for industrial applications when forced ventilation is impossible due to environmental constraints. Attached to a chassis or a cold plate, the OFI1200A model can deliver considerable power with very high reliability.

The power supply is certified to UL62368-1 3rd edition, cUL (equivalent to CAN/CSA-22.2 No.62368-1).

The OFI1200A series of power supplies are backed by a three-year warranty and comply with European RoHS, REACH and Low Voltage directives. The product has CE, UKCA and cURus markings.
