Mean Well DDRH-240-32 Ultra Wide Input DC-DC Converter, 240W 32V
The DDRH-240 is a 240W high-reliability ultra-wide input DIN Rail DC-DC converter for photovoltaic, energy storage, and high-voltage industrial applications. Its 250~1500Vdc input range handles high-voltage DC bus and battery string sources, with 4KVac reinforced I/O isolation for reliable, noise-free operation. Up to four units can be paralleled for current sharing up to 960W, and a DC OK relay output provides supply status monitoring. The DDRH-240 operates fanless across -40~+80℃.

Frequently Asked Questions
What types of industrial loads are compatible with the DDRH-240-32's 32V output?
The DDRH-240-32 is suited for 32V DC loads such as certain brushless DC motors, specialized industrial actuators, and telecom or datacom equipment that operates at 32V. At 240W and 7.5A, it can handle mid-range power loads in these categories. The output is adjustable from 30V to 36V, adding flexibility for loads at the higher end of this range.
Can the DDRH-240-32 accept power from a photovoltaic or high-voltage DC battery bus?
Yes. The DDRH-240-32 accepts 250–1500VDC input with a 6:1 ultra-wide range and can withstand 1700VDC surge for 10 seconds. This makes it compatible with high-voltage photovoltaic string outputs and DC battery buses used in renewable energy and energy storage systems.
Is the DDRH-240-32 appropriate for embedded systems or industrial computing that requires 32V supply?
Yes. For industrial embedded platforms or custom hardware designed around a 32V rail, the DDRH-240-32 provides 240W at 7.5A in a compact DIN rail-mount package with an 85.5mm slim width. Its fanless, wide-temperature design also suits enclosed cabinet deployments where heat management is critical.
Can the DDRH-240-32 operate in extreme-temperature industrial environments?
Yes. The DDRH-240-32 is rated for -40°C to +80°C operation, making it appropriate for applications ranging from sub-zero outdoor equipment enclosures to high-ambient factory floors. The unit should be housed in an IP-rated enclosure when installed in environments with moisture or particulate exposure.
How do the four 240W DDRH models compare across output voltages?
The 240W DDRH models are: DDRH-240-12 (200.4W, 12V, 16.7A), DDRH-240-24 (240W, 24V, 10A), DDRH-240-32 (240W, 32V, 7.5A), and DDRH-240-48 (240W, 48V, 5A). All use the same 250–1500VDC input range, 85.5mm DIN rail width, and carry CE/EAC certifications. Selection is based on the output voltage required by the application.
