CH-FAN-037-380 Fan control cabinet 37 kW 380 V

A 37 kW fan cabinet on a 380 V supply in an Eliton MKN 1284 wall enclosure, 1200x800x400 mm, IP54. Cooling is sized with a 1.5x margin over drive losses.

What is inside

• Veichi AC310 variable frequency drive, article AC310-T3-037G/045P: 37 kW, 380 V input, 75 A rated current, built-in PID regulator
• Schneider Electric three-pole input circuit breaker, 125 A
• Enclosure: Eliton MKN 1284, 1200x800x400 mm, IP54, wall mounting, painted steel
• Cooling: forced ventilation 500 m3/h with a thermostat
• Installation kit: DIN rails, slotted cable ducts, power and signal wiring, cable glands, start and stop buttons, door status lights
• Drive parameters set for the motor, circuits labelled, and the cabinet tested before dispatch

How the speed is set

There is no liquid-pressure sensor here. A fan does not need one: a precision 10 kOhm potentiometer sits on the door and the operator sets the speed by hand. If controls are added later (duct pressure sensor, CO2, a BMS), their 0-10 V or 0(4)-20 mA signal goes to the same analogue input on the drive, while the fault signal is taken from the drive's relay output. A manual/auto selector is fitted on the door.

Options on request

• an output motor choke when the motor cable runs longer than 30-50 m
• a braking resistor for fast stops and high-inertia loads
• a three-contactor mains/drive bypass with mechanical and electrical interlock
• a remote operator keypad on the cabinet door
• an outdoor package: enclosure heater, second thermostat, rain hood

These are agreed separately. Write to us if the build has to change and an engineer will price the exact scope for your site, while the standard article number stays as it is, so a modified cabinet is quoted as its own line.

Lead time, warranty, documents

Build time is 7-10 working days. The clock starts at order confirmation. The assembled cabinet carries a 24-month warranty under the store's general warranty terms, and a wiring diagram plus a list of installed components ship with it, because there is no separate operating manual for the series: the build changes from order to order. We assemble the cabinet at our premises, parameterise it, run it under load. We do not travel to site. Your electrician wires it up and starts it. We support that remotely.
