Off-the-shelf UPS units don't always meet complex industrial site constraints. Helios Power Solutions specializes in customizing AC UPS hardware, power distribution enclosures, and network communication mapping for global engineering contractors (EPCs) and system integrators.
Online Double Conversion (VFI - Voltage and Frequency Independent) continuous operation completely isolates sensitive loads from utility power line disturbances, voltage fluctuations, harmonic distortion, and frequency shifts. AC power is rectified to DC and inverted back to pure sine wave AC output with zero transfer time (0ms switchover), ensuring zero risk to mission-critical instruments, PLCs, and SCADA hardware.
A Static Transfer Switch (such as the Helios iSTS series) monitors two independent AC power sources and automatically transfers connected loads to a secondary source in less than 4 milliseconds upon main source failure or degradation. This sub-cycle switchover occurs faster than the hold-up time of industrial power supplies, preventing operational interruption without requiring battery storage.
Yes. Our high-temperature industrial outdoor AC UPS platforms (such as the TC Series) are engineered with heavy-duty thermal management, conformal-coated PCB boards, ruggedized IP-rated metal enclosures, and high-temp battery chemistry designed to operate reliably in harsh ambient environments from -20°C up to +55°C.
Helios engineers AC UPS systems supporting single-phase input/output (100V, 110V, 120V, 220V, 230V, 240V at 50Hz/60Hz) and three-phase industrial inputs/outputs (380V, 400V, 415V, 480V). Custom galvanic isolation transformers can also be integrated to match local grounding and isolation standards worldwide.
