Solving Power Specification Mismatches
Standard datasheets rarely align perfectly with tough field realities. Harsh operating ambients, restrictive mechanical footprints, specialized battery chemistry charging, and complex SCADA alarm mappings require dedicated engineering solutions.
- Electrical Engineering: Custom input/output voltage rating, ultra-low ripple, N+1 redundancy, and extended hold-up times.
- Mechanical Customization: 1U to 42U rackmount enclosures, wall-mount chassis, outdoor NEMA/IP-rated cabinets, and shock/vibration mitigation.
- SCADA & Comms Integration: DNP3, Modbus RTU/TCP, SNMP v2c/v3, and user-configurable volt-free alarm contacts.
- Environmental Protection: Tropicalization, conformal-coated PCBs, wide operating temperatures (-40°C to +75°C), and rugged military hardening.

Technical Procurement FAQ
Custom Power Solutions Questions
Helios engineers electrical re-ratings (custom DC/AC voltages, current capacities, hold-up times), enclosure customizations (IP rating, 19-inch rack, wall mount, shock/vibration mitigation), conformal coating for hostile environments, and protocol mapping (DNP3, Modbus RTU/TCP, SNMP, dry contacts) for seamless SCADA integration.
Every custom power design undergoes stringent in-house testing governed by our ISO 9001:2015 quality system. Options include full Factory Acceptance Testing (FAT) witnessed in-person or remotely, thermal stress testing, full load burn-in, dielectric isolation testing, and protocol verification against customer SCADA configurations.
Our custom power systems are widely deployed in Electrical Power Utilities, Defence & Military platforms, Railway Signal & Traction control, Oil & Gas offshore infrastructure, Remote Telecommunications, and OEM heavy industry automation.
Lead times vary depending on the complexity of mechanical fabrication and component sourcing. Minor modifications to standard platforms take as little as 2 to 4 weeks, while fully customized MIL-spec or complex multi-cabinet power plants are delivered within engineered project schedules.
