Mean Well DC-DC Converters DDR-30 Series Supplier
SCB Industries is a trusted and authorized Mean Well DDR-30 Series DC-DC Converter supplier serving Kolkata, West Bengal, Odisha, Bihar, Chhattisgarh, Assam, Gujarat, Pune, and Vapi. We deliver genuine Mean Well DDR-30 modules that bring compact DIN-rail power conversion, high reliability, and easy integration to industrial control panels, automation systems, telecom, and transport applications.
What is the Mean Well DDR-30 Series?
The DDR-30 family is a 30 W, DIN-rail mount DC-DC converter series from Mean Well. These modules convert a DC input to a stable, regulated DC output with electrical isolation. DDR-30 units are built for industrial use where space is limited but reliable, isolated DC power is required. The series is available in two main variants:
- DDR-30G— wide / 4:1 input range (for systems with variable DC rails)
- DDR-30L— standard / 2:1 input range (for stable DC bus systems)
DDR-30 series is a 30W DlN Rail type DC-DC converter with main features including DlN rail-type easy installation, ultra slim width (35mm), 4:1 ultra wide input voltage, -40~+85℃ wide operating temperature, 4KVdc l/O isolation, adjustable output voltage (± 10%) and full protective functions…etc.
This series has two input options: 9~36V /18~75V and various output options: 5V / 12V / 15V / 24V and can be used for industrial control, security control, communication system and other fields. Suitable applications are DC buck/boost regulator, increasing system insulation level and voltage drop compensation along cable…etc.

Benefits — why engineers pick the DDR-30
- Reliable, regulated DC powerfor PLCs, I/O modules, sensors and communication devices.
- Space efficiency— DIN-rail mounting saves panel space and simplifies wiring.
- Lower system noise & heatthanks to high efficiency and fanless cooling.
- Safer systemsthrough galvanic isolation between input and output.
- Flexible integrationwith remote ON/OFF and standard industrial approvals.
- Low maintenance— rugged build and convection cooling reduce lifetime servicing.
DDR-30 Types — DDR-30G vs DDR-30L
DDR-30G Series
The DDR-30G models are designed to operate with a wide DC input voltage range. They offer exceptional flexibility for systems where DC input can fluctuate significantly.
Technical Overview:
- Input Voltage Range:9~36VDC or 18~75VDC (depending on model)
- Output Voltages Available:5V, 12V, 15V, 24V
- Output Power:30W
- Efficiency:Up to 90%
- Isolation Voltage:1500VDC
- Cooling Method:Convection
- Protections:OVP / OCP / SCP / OTP
- Certifications:UL62368-1, EN62368-1, EN55032, EN55035
DDR-30G (4:1 wide input)
- Input range:Wide 4:1 (commonly options like 9–36 VDC or 18–75 VDC)
- Output voltages available:typical choices 5 V, 12 V, 15 V, 24 V (model dependent)
- Efficiency:slightly higher potential due to optimized wide-range design (typical up to ~89%)
- Best for:systems with variable DC sources (battery banks, solar/battery hybrid, mixed-voltage buses, vehicle applications, remote equipment with fluctuating supply)
- Advantages:single SKU can cover many input rails — simplifies spares and design flexibility
DDR-30L Series
The DDR-30L models are intended for systems where the DC input is stable. They offer high reliability at a more economical cost compared to the wide-range models.
Technical Overview:
- Input Voltage Range:9~18VDC or 18~36VDC (depending on model)
- Output Voltages Available:5V, 12V, 24V
- Output Power:30W
- Efficiency:Up to 88%
- Isolation Voltage:1500VDC
- Cooling Method:Convection
- Protections:OVP / OCP / SCP / OTP
- Certifications:UL62368-1, EN62368-1
DDR-30L (2:1 standard input)
- Input range:2:1 (commonly 9–18 VDC or 18–36 VDC)
- Output voltages available:typical 5 V, 12 V, 24 V
- Efficiency:very good (typical up to ~88%)
- Best for:installations with stable DC buses (factory PLC racks, fixed-voltage control cabinets)
- Advantages:cost-effective when wide input range is not required
Practical Differences
- Flexibility:DDR-30G > DDR-30L
- Cost:DDR-30L usually slightly more economical for fixed-voltage applications
- Use cases:DDR-30G for mobile/variable-power and distributed systems; DDR-30L for stable-panel installations
- Spares strategy:using DDR-30G can reduce SKU count where multiple input rails exist
Typical Applications
- Industrial automation and control cabinets
- PLC power supplies and I/O clusters
- Remote monitoring and telemetry equipment
- Transportation and vehicle electronics (where DC rails vary)
- Renewable & battery-powered systems (microgrids, solar + battery)
- Telecom and network edge devices
- Building management and security systems
