Fan Control for EC Motor, Stepless Speed Regulation for Fans, 0-10/12 V, Harmann

Quick Facts — H-MTP-10 Fan control

• Model: H-MTP-10
• Type: Potentiometer for EC fans
• Control range: 0-12 VDC
• Resistance: 10 kΩ
• Supply: Built-in 12 V
• Extra function: Switch for external devices

The H-MTP-10 fan control from Harmann is a potentiometer for stepless speed regulation of EC-motor fans, from 0 to the input voltage level within 0-12 VDC. It has a built-in 12 V supply and connects directly to the fan.

The control works with EC fans from several manufacturers that accept a 0-10 V or 0-12 V control signal, such as the ML EC.A. It suits residential, commercial and industrial installations, and its compact design makes it easy to integrate into ventilation setups.

What sets fan control H-MTP-10 apart?

Yes, the H-MTP-10 gives stepless regulation without fixed positions, using a 10 kΩ potentiometer. Its own 12 V supply allows the fan to be connected directly without an external voltage source.

The control also has an integrated switch that can be used for remote control of external devices. The construction is intended for long-term use.

How fan control H-MTP-10 is used in ventilation systems

The H-MTP-10 is used to match fan speed to demand in ventilation systems with EC fans. The benefits are:

• Precise control of fan speed across the whole 0-12 VDC range.
• Better energy efficiency and comfort through adapted speed.
• Use in residential, commercial and industrial installations.

Technical Specifications

Used by: Ventilation installers, electricians, maintenance technicians and facility caretakers.

Common in: The ventilation trade, property management, commercial premises, industry and residential ventilation.

Frequently Asked Questions (FAQ)

Does fan control H-MTP-10 work with fans that have a capacitor motor?

No, the control is intended for EC fans with a 0-10 V or 0-12 V control signal. Capacitor motors may hum and become warm, especially at very low speeds. In that case the speed should be raised or a 5-step controller with fixed positions used.

Is fan control H-MTP-10 suitable for EC fans with a 0-10 V control signal?

Yes, the H-MTP-10 regulates steplessly within 0-12 VDC and works with EC fans that accept 0-10 V or 0-12 V, such as the ML EC.A. The built-in 12 V supply allows direct connection.

What distinguishes fan control H-MTP-10 from other speed controllers?

The H-MTP-10 regulates steplessly with a 10 kΩ potentiometer, whereas 5-step controllers have fixed positions. It is made for EC motors, has a built-in 12 V supply and a switch for remote control of external devices.
