Representative imageCustomised Frequency Converters
Customised frequency converters are made-to-order static converters engineered to a customer's exact electrical and mechanical requirements rather than a fixed catalogue rating.
Overview
Customised frequency converters are made-to-order static converters engineered to a customer's exact electrical and mechanical requirements rather than a fixed catalogue rating. ACE designs the input/output voltage class, number of phases, power rating (kVA), and the precise input and output frequency combination (e.g. 50->60Hz, 60->50Hz, or 50/60->400Hz) to suit a specific machine, test rig, or installation. Customisation typically extends to the output voltage range and regulation, waveform/THD targets, cooling method, enclosure (IP rating, dimensions, shock-mounting, casters for portability), and protection and metering features. Buyers choose a customised converter when off-the-shelf ratings don't match an imported machine, a defence/aerospace platform demands compliance with specific military standards, or an installation needs a particular cabinet form factor and interface — getting a single unit that does both voltage and frequency conversion exactly to spec.
Specifications
| Built to order | input/output voltage, phases, kVA and frequency combination specified by the buyer |
|---|---|
| Power rating | sized to load, from a few kVA up to several hundred kVA (multi-hundred-kVA on request) |
| Type | static / solid-state, two-stage AC-DC-AC, pure sine-wave output |
| Phases | single- or three-phase in/out, configurable per application |
| Input voltage/frequency | specified to local supply (e.g. 230/415/440/480 V at 50 or 60 Hz) |
| Output frequency | any required fixed value — commonly 50 Hz, 60 Hz or 400 Hz |
| Output voltage | customised range and tap/regulation (e.g. 115/200 V, 120/208 V for 400Hz; adjustable on request) |
| Output regulation/stability | voltage typically ±1%, frequency typically ±0.01-0.5% (to spec) |
| THD / efficiency | target waveform purity and efficiency specified per project |
| Cooling & enclosure | forced-air or as required; custom cabinet size, IP rating (IP20-IP55), shock isolators, casters |
| Protections & metering | over/under-voltage, overload, short-circuit, over-temperature; instrumentation to order |
| Standards/compliance | IS/IEC, IEEE-519/IEC 61000 harmonics; MIL-STD-704 / 810 / 1399 for defence/aerospace/marine builds |
Applications
- Imported or special-purpose machinery needing a non-standard or exact supply frequency/voltage
- Aerospace and avionics 400Hz ground-power and test setups with bespoke ratings
- Defence and naval platforms requiring MIL-STD-compliant, application-specific converters
- OEM integration where a particular cabinet, interface, or footprint is mandated
- Specialised test benches and R&D installations with unique power requirements
