DEZ/DIZ ignition transformers for gas and oil burners, up to 15 kV

Country: Germany · Model: DEZ / DIZ

DEZ (electronic) and DIZ (inductive) ignition transformers deliver a spark of up to 15 kV for igniting gas and oil burners. DEZ units are powered from 230 or 120 V AC, and DIZ units have an output of 8 kV, 2×4 kV or 5 kV. They work together with burner control units, for example MPA 41xx.

Description

DEZ delivers 15 kV or 2×14 kV at a current of 20–30 mA, and DEZ 100/SEO and DEZ 101/SEO allow single-electrode mode, where one electrode serves both for ignition and for ionization flame monitoring. DIZ units are inductive, with a current of 12–20 mA, and the range includes DIZ 100, DIZ 200, DIZ 101 SEO (including in an IP65 housing), DIZ 110 SEO and DIZ 111 SEO for 115 V. The duty cycle depends on the model: 19 % with a 3-minute cycle, 25 % with 4 minutes, 33 % with 3 minutes, or 100 %. The electrodes are connected single-pole or two-pole, and the electrical connection is made with a plug connector, a molded cable or screw terminals. For DEZ, mains cables of 265–5000 mm and ignition cables with a carbon fiber (CFC) or copper conductor of 370–3000 mm, terminals and angled caps are supplied. North American versions have UL registration and a CSA certificate.

How to choose

First the mains voltage and the method of flame monitoring are checked. For a 230 or 120 V supply DEZ is used, and for a 115 V network there is DIZ 111 SEO. If the flame is monitored through the same electrode, the SEO version is needed. The protected IP65 housing is offered by DIZ 101 SEO, and the cable length is chosen from the ranges 265–5000 mm and 370–3000 mm.

FAQ

What is the output voltage of DEZ and DIZ transformers?

DEZ delivers 15 kV or 2×14 kV, DIZ delivers 8 kV, 2×4 kV or 5 kV.

What does the SEO version mean?

Single-electrode mode, where one electrode serves both for ignition and for ionization flame monitoring. Such versions exist in DEZ 100/SEO, DEZ 101/SEO and DIZ 101 SEO.

What is the duty cycle of the transformers?

It depends on the model: 19 % with a 3-minute cycle, 25 % with 4 minutes, 33 % with 3 minutes, or 100 % (continuous operation).

What approvals do the ignition transformers have?

CE and UL, and North American versions also CSA. The database contains EAC and UA certificates.
