Mean Well DDRH-240-12 Ultra Wide Input DC-DC Converter, 200.4W 12V
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
Can the DDRH-240-12 power industrial 12V DC bus loads in a rail-mounted control cabinet?
Yes. The DDRH-240-12 delivers 200.4W at 12V and 16.7A on a DIN rail form factor with an 85.5mm slim width, making it suitable for mounting alongside PLCs and I/O modules in industrial control cabinets. Its 6:1 ultra-wide input range (250–1500VDC) allows it to accept power from a wide variety of DC bus sources found in industrial environments.
Is the DDRH-240-12 suitable for powering embedded computing or networking equipment in a 12V system?
Yes. At 200.4W and 16.7A output, the DDRH-240-12 can handle mid- to high-power embedded systems, industrial PCs, or networking switches that operate at 12V. The output voltage is also adjustable from 12V to 15V, providing some flexibility for load tuning without changing the unit.
Can this converter handle high-voltage DC inputs from a solar or battery storage bus?
Yes. The DDRH-240-12 accepts 250–1500VDC input with a 6:1 ratio ultra-wide range and can withstand a 1700VDC surge input for up to 10 seconds. This makes it well-suited for high-voltage DC sources such as solar string inverters or battery bank buses commonly found in energy storage and off-grid installations.
Can the DDRH-240-12 be used in outdoor enclosures or harsh environments?
The DDRH-240-12 operates across -40°C to +80°C, making it rated for extreme temperature environments. However, no IP rating is listed, so the unit should be installed inside a suitably rated protective enclosure if deployed outdoors or in areas with moisture or dust ingress.
How does the DDRH-240-12 compare to the other 240W models in the DDRH series?
The DDRH series includes three 240W models: DDRH-240-12 (200.4W, 12V, 16.7A), DDRH-240-24 (240W, 24V, 10A), and DDRH-240-48 (240W, 48V, 5A). All share the same 250–1500VDC input range, 85.5mm DIN rail width, and CE/EAC certifications. The choice depends on the output voltage required by the load.
