Micron universal voltage series through 750 VA.
Source: Micron Industries control transformer cross reference for Dongan, March 2018. Micron units through 750 VA are ImperviTRAN or ValuTRAN, 105°C construction, with 13/32 x 1-1/2 in secondary fuse clips where applicable and a class CC primary fuse block option. * Micron has no 375 VA standard; the sheet lists the 350 VA unit, so check your load or step up to 500 VA. The sheet prints some EconoTRAN numbers with a letter O; the Micron numbers use a zero. The Dongan 058 series (415/380/220 V primary) has no direct Micron standard; send the number and we cross it. 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 50 series number
50 is the Dongan machine tool control transformer line. The middle four digits are the VA (0250 is 250 VA). The last three digits are the voltage series: 053 is 230 x 460 V to 115 V, 054 is 208 V to 120 V, 056 is 600 V to 120 V, 059 is a multi-tap universal unit. 50-0250-053 crosses to Micron B250BTZ13JK.
Common questions
What Micron transformer replaces Dongan 50-0100-053?
Micron B100BTZ13JK, 100 VA, Group A. Primary 220x440, 230x460 or 240x480 V. Secondary 110, 115 or 120 V.
What replaces Dongan 50-0050-053?
Micron B050BTZ13JK, 50 VA, Group A.
What replaces a Dongan 056 600 V transformer?
Micron Group E, the WZ13XK series: 550/575/600 V primary, 110/115/120 V secondary. 50-0100-056 crosses to B100WZ13XK.
Does Micron make a 375 VA control transformer?
No 375 VA standard. Check the load; the sheet lists 350 VA, and 500 VA gives more margin.
