REC3-243.3SRWZ/H2/A/M/SMD/CTRL-R

The REC3-243.3SRWZ/H2/A/M/SMD/CTRL-R is a DC-DC converter for industrial use. It is designed to convert an input voltage of 24 VDC or 48 VDC into an output voltage of 24 VDC, 48 VDC, 60 VDC, or 72 VDC, with a maximum load current of 243.3A. This unit is commonly used in applications such as rail traction, battery chargers, electric and hybrid vehicles, and mining equipment.

The REC3-243.3SRWZ/H2/A/M/SMD/CTRL-R is an open-frame converter, meaning it is exposed and not encased in an enclosure. It features voltage scaling, current sharing, maximum load current, short-circuit protection, overload protection, and a high efficiency of 98%. The size of the unit is relatively small for its power capacity of 6 kW, occupying only 16 cm x 32 cm of space.

This DC-DC converter contains a wide input voltage range of 18-75 VDC and a wide temperature range of -40 oC to +85 oC. The power factor correction supports PF>0.99, and the no-load input current is less than 3.6 A. The output voltage can be adjusted through a rotary control on the side of the unit. It also features active current sharing between all four outputs to evenly distribute the load.

The REC3-243.3SRWZ/H2/A/M/SMD/CTRL-R utilizes a two-stage conversion technology. During the first stage, an active PFC utilises a DC/DC boost converter with high power factor to regulate the input voltage and adjust it according to the desired output voltage. During the second stage of conversion, a DC/DC buck converter reduces the voltage and produces the output.

The REC3-243.3SRWZ/H2/A/M/SMD/CTRL-R is designed for a long lifetime operation (250,000 hrs) to facilitate reliable operation. The internal electronics are also designed to minimize thermal derating. This converter also comes with an intelligent management module that prevents overloads and overtemperature and can be used with exterior controllers that monitor the voltage output.

The REC3-243.3SRWZ/H2/A/M/SMD/CTRL-R is a reliable and efficient DC-DC converter with a long lifetime and small footprint. Its wide input voltage range and active current sharing capabilities make it a suitable choice for many industrial applications. Its two-stage conversion technology ensures that the output voltage remains consistent, even under varying input conditions.
