Honeywell ET401A electronic ignition transformer
Introduction:
ET serial ignition transformer with high voltage cable connection pin and power cable, suitable to be installed in burner control box, can be wildly used with oil, gas
and dual fuel burners. Enables big spark deformation on burners with a high fire-rating or high combustion-air velocity. In addition to this, it generates the lowest electromagnetic interferences of all known electronic ignition devices, which is especially important if the
burner has to comply with EN 55014-2. ET serial ignition transformer combines a low power consumption with a low inrush current. The operation must be intermittent ignition, work-cycle limit of 3 minutes, in which the ignition time is less than 1 minute, it means 33 % E.D. in 3 minutes.
Features:
ET serial ignition transformer adopt transistorised oscillator to produce a high frequency voltage which is then increased to 14 kV, compare with conventional iron cored transformer, despite they are very compact dimensions, they have outstanding performance. The
dimensions of the housing and fixing holes are such that it can be mounted underneath the burner control box wiring base. ET serial ignition transformer supply with 3 cores power
cable, ET401 has 1 high voltage output pin connection, suitable for use with gas burners. ET402 has 2 high voltage output pin connections, suitable for use with oil, gas and dual fuel burners. The pin diameter is 1 mm (Show in dimension drawing). Connect with high
voltage cable with fasten clip.
Installation instruction:
The applicable regulations must be observed when mounting the device and carrying out the electrical connections. Particular attention must be given to method used to install the H.T. cables. Avoid unnecessary lengths, sharp bends over hard edges,extremely high temperatures etc., any of which could give rise to reduced performance or possible problems.The length of power line is about 0.5 m, connect the wires with their terminals: brown-live wire, blue-null wire, yellow/green-ground wire.For trouble-free operation, the correct spark gap at the ignition electrodes must be observed, supply voltage reductions of minus 15% and low as well as high ambient temperatures can give rise to problems The
positioning of the H.T. ignition cables with regard to TV and radio interference is also extremely important. The cables should be kept short, run as close together as possible and should not cross or be in contact with any other power cables or fittings. See "Technical data" for recommended settings
