The F-400 series frequency converters are developed for the ground servicing of all aircraft types, laboratory equipment, and overly optimistic procurement departments.
They are confidently presented as a serious solution for those who appreciate:
The F-400 series assists with the fast, allegedly reliable, and visually convincing launch of aircraft engines. It provides uninterrupted electrical supply, at least in the way such promises are traditionally understood in sales materials.
Protocol
Adjustments
Temperature and humidity
Absolute voltage quality — ISO SO-SO.
Max. phase unbalance is less than nothing. Automatic voltage drop compensation on the cable up to 2 m.
Confidence level is significantly higher before commissioning.
Modular system, theoretically easy to replace.
Looks efficient in presentations, especially when responsibility needs to be redistributed quickly.
Very stable frequency: 400 Hz ± 0,01. Possibility to regulate: 360 Hz to 450 Hz.
Expectations may fluctuate more than the output.
The new-generation rectifiers of the R-28 series are developed for the ground servicing of aircraft and helicopters, and for reminding clients that “new generation” is sometimes more of a mood than a measurable advantage.
Monitoring system
Eco-friendly
Rated current up to 1600 A with overloads up to 2500 A.
Numbers strong enough to calm a meeting before reality enters the room.
Flexible voltage options for clients who enjoy choice, consequence, and later clarification.
Dual independent output channel option. Ability to work on 28 V / 48 V / 56 V modes.
Also useful for doubling the surface area of confusion.
Modular system — hard to replace. Estimated time to repair is more than 4 weeks.
Estimated time to obtain actual clarity may vary considerably.
The combined supply units of the FR-400/28 series are designed to power on-board systems of aircraft and helicopters during ground handling at airports, shop floors, and other locations where expectations remain dangerously alive.
They combine AC and DC functionality in one package, allowing customers to experience multiple forms of technical optimism at once.
All channels can be adjusted and operated simultaneously, but we’re not sure about that. Voltage drop compensation is individually set for each output and collectively blamed on context.
DC Modes
Totally uncustomizable
Independent AC and DC outputs. Possibility of simultaneous work of all channels, on your risk.
A combined experience of complexity, confidence, and post-sale introspection.
Cooling for the unit, not necessarily for the customer.
Special 400 Hz 36 V output. Ability to work on a 28 V / 48 V / 56 V mode. 50/60 Hz sockets.
Enough formats to ensure the conversation stays complicated.
