We develop comprehensive and sustainable manufacturing solutions for your PCB projects

When you need experience, we have it covered.

Check our past projects and the PCBs that we have manufactured for our clients in the power and energy industry 

Battery Management System (BMS)

  • Battery Management System (BMS) PCBs – Handle cell monitoring, balancing, and protection in battery packs.
  • Thermal Sensing PCBs – Integrate temperature sensors (NTCs, RTDs) and manage active cooling elements.
  • Battery Protection PCBs – Provide overcharge, overdischarge, and short-circuit protection layers.
Energy storage systems (ESS)
  • Battery Management Systems (BMS) for ESS – Monitor and balance large arrays of battery cells to ensure safe energy storage and delivery.
  • Thermal Management PCBs – maintain optimal operating temperatures across the storage system.
  • Protection & Safety Circuit PCBs – Rapidly detect faults and activate protective measures like circuit breakers.
Electric Vehicle (EV) Infrastructure
  • On-board Charger (OBC) PCBs – Convert external AC power to DC for in-vehicle battery charging.
  • EV Fast Charger PCBs – Control high-current DC charging with thermal and communication management.
  • Vehicle Control Unit (VCU) PCBs – Integrate propulsion, safety, and energy management systems inside EVs.
Renewable Energy Systems
  • Solar Charge Controller PCBs – Manage power from solar panels to batteries or loads efficiently.
  • Wind Turbine Control PCBs – Oversee blade pitch, braking, yaw systems, and output regulation.
  • Hybrid System Controller PCBs – Integrate solar, wind, and backup sources into a coordinated energy system.
Power Conversion & Regulation
  • DC-DC Converter PCBs – Step up or step down voltages between system components efficiently.
  • AC-DC Converter PCBs – Convert alternating current into stable direct current for storage and use.
  • Inverter PCBs (DC-AC) – Transform stored DC energy into AC power for grid or load supply.
High Voltage & Grid Control
  • High Voltage Switching PCBs – Manage the control of circuit breakers, contactors, and relays under high voltages.
  • Insulation Monitoring PCBs – Continuously check for insulation faults in HV systems.
  • Voltage/Current Sensing PCBs – Measure and report critical electrical parameters
