A major renewable energy developer approached Relec Electronics during the design phase of their next-generation photovoltaic (PV) and energy storage systems (ESS). Their objective was clear but challenging: they needed a power electronics that could adapt to ultra-high input voltages while maintaining safety, efficiency, and reliability in extreme environments. The application requirements were:

Ultra-wide input voltage
(150 – 1500 Vdc)

High-altitude operation
(up to 5000m)

Certified safety compliance for global installations

Relec Electronics worked closely with the customer to identify Cincon’s DH Series DC-DC converters as a comprehensive solution. These converters were tailored to meet the demands of renewable energy systems, offering robust performance and industry-leading features.

DH30W10

Input: 150 – 1500 Vdc
Output: 24V @ 12.5A
Isolation: 4000 Vac
Cooling: Fully encapsulated for durability

dh45w10

Input: 150 – 1500 Vdc
Output: 48V @ 14.6A
Isolation: 4000 Vac
Compliance: UL1741, EN62109

The client selected the 30W model for their solar tracking systems and the 45W model for their ESS. Relec ensured the configurations would integrate seamlessly into their existing infrastructure.

Relec’s engineering team provided hands-on support to streamline integration. The units were delivered ahead of schedule, enabling the customer to conduct extensive pre-deployment testing.

The results were exceptional:

Efficiency

Reduced energy losses across fluctuating voltage inputs.

Adaptability

Reliable performance at high altitudes and extreme temperatures.

Compliance

Full certification met the regulatory demands of international markets.

“Relec’s technical expertise and support helped us tackle challenges we couldn’t solve alone. The DH Series has been a game-changer in our renewable energy systems.”
