DDRH-120/240 Series, 120W, 240W DIN Rail Type DC-DC Converter

In recent years, the demand for renewable energy such as photovoltaics and energy storage has increased drastically. As a response, MEAN WELL launched the DDRH-60 and RSDH-150/300 (details in table below) subsequently. Now we are launching a new 120W/240W ultra-wide 250~1500Vdc high voltage input DIN rail DC-DC converter, the DDRH-120/240 series.

DDRH-120/240 series key features include: 250~1500Vdc ultra-wide input range, fanless design operational in -40～+80°C wide temperature range, 4KVac high isolation level, input/output complete protection features, superior EMC performance, high altitude 5000M operation, and compliance to the IEC/EN62109-1 PV safety. These features enable the DDRH-120/240 series to be suitable for PV, energy storage, charging station, and other applications that have high voltage to low voltage DC conversion requirement.

Features:

• 250~1500Vdc ultra-wide input voltage
• 4KVac I/O isolation
• Free air convection, can operate between -40~+80°C (+50°C@full load without derating), suitable for various installation conditions
• Fanless design, no noise
• Excellent EMC performance, meet EN55032 Class A EMI performance without external components
• Built-in potentiometer, can trim output (12~15V,24~29V,30~36V,48~58V)
• Protections:
  • Trimming output voltage ± 10%
  • Input – Under voltage protection, reverse polarity (No damage)
  • Output – Short circuit, overload, over voltage, over temperature
• Approvals: CB/DEKRA (IEC/EN62109-1), EAC, CE, UKCA
• 3 years warranty
