Dongan IC Century Control Transformer Cross Reference to Micron

Dongan IC Century series control transformers cross to Micron by VA and series. IC-0100-103 (100 VA, 230 x 460 V to 115 V) crosses to Micron B100BTZ13JK. The middle four digits are the VA. The last three are the series. A series in the 120s (122, 123, 127, 129) has a class CC primary fuse block installed; the matching 100s series (102, 103, 107, 109) does not.

For Dongan 50 series numbers (50-0100-053 and the like), use the Dongan 50 series cross. For HC numbers, use the Dongan HC cross.

Dongan IC-123: 230 x 460 V primary, 115 V secondary, class CC primary fuse block installed

Micron Group A with the RB option: class CC primary fuse block installed.

Dongan IC-102: 120 x 240 V primary, 24 V secondary

Micron ImperviTRAN Group C: 120 x 240 V primary, 24 V secondary. At 1 kVA, send the number and we check it with Micron.

Dongan IC-122: 120 x 240 V primary, 24 V secondary, class CC primary fuse block installed

Micron Group C with the RB option: class CC primary fuse block installed.

Dongan IC-107: 230 x 460 V primary, 115/230 V secondary (triple rated)

Micron ImperviTRAN Group K: 240 x 480 V primary, 120 x 240 V secondary through 750 VA. Group M (230 x 460 V to 115 x 230 V) at 1 kVA and up.

Dongan IC-127: 230 x 460 V primary, 115/230 V secondary, class CC primary fuse block installed

Micron Group K with the RR option: class CC primary fuse block installed.

Dongan IC-109: 380/400/415 V primary, 110/220 V secondary

Micron ImperviTRAN Group I: 380/400/415 V primary, 110 x 220 V secondary.

Dongan IC-129: 380/400/415 V primary, 110/220 V secondary, class CC primary fuse block installed

Micron Group I with the RJ option: class CC primary fuse block installed. * Micron has no 375 VA standard. The sheet lists the 350 VA unit. Check your load, or step up to 500 VA.

Source: Micron Industries cross reference for the Dongan Century (IC) series machine tool control transformers, from the Micron LVGP and control transformer cross reference file (2016 edition). Dongan lists the IC series as 105°C construction, UL, cUL and CE, with no installed secondary fuse clips and a 10 year warranty. Micron ImperviTRAN units are 105°C through 100 VA and 130°C above, with 13/32 x 1-1/2 in secondary fuse clips where applicable and a 20 year warranty. Where Dongan uses a 375 VA size the sheet lists Micron 350 VA. The sheet prints the 100 VA IC-127 match as B100PU1519R; by the series pattern it is B100PU1519RR. We confirm on the quote. F and H suffixes add secondary fuse clips; we confirm the exact suffix on every quote. Linked Micron numbers open the part we list at the same VA and voltage. Our listing can carry an added suffix letter (for example B150BTZ13JKF); we confirm the exact suffix on every quote.

How to read a Dongan IC number

IC is the Dongan Century machine tool control transformer. The middle four digits are the VA (0250 is 250 VA, 0375 is 375 VA). The last three digits are the series: 102 is 120 x 240 V to 24 V, 103 is 230 x 460 V to 115 V, 107 is 230 x 460 V to 115/230 V, 109 is 380/400/415 V to 110/220 V. Add 20 (122, 123, 127, 129) for the same voltage with a class CC primary fuse block. IC-0250-123 is 250 VA, 230 x 460 V to 115 V with a CC fuse block, and crosses to Micron B250BTZ13RBF.
