PWDP13026 is an extra heavy-duty replacement plate transformer for the Heath HL-2200, built with a 7 mil C-core and listed as the same fit as the SB-220, SB-221 and HL-2200. The drawing identifies it as the Heathkit SB-220-3-7 plate transformer (PT-220). Note that the listing states it requires modification to the chassis.
The primary accepts 117 or 234 VAC at 60 Hz, with HI and LO taps, via six #14 TEF black leads (1 COM, 2 HI, 3 LOW, 4 COM, 5 HI, 6 LOW). The secondary is 860/1171 VAC at 1.3 A CCS on #18 SIL red leads 7 and 8. Jumpering selects the output: for 117 VAC HI, jumper 1-4 and 2-5 and excite 1 and 2; for 117 VAC LOW, jumper 1-4 and 3-6 and excite 1 and 3; for 234 VAC HI, jumper 2-4 and excite 1 and 5; for 234 VAC LOW, jumper 3-4 and excite 1 and 6.
No-load secondary test voltages are 1183 V (HI) and 887 V (LOW), each ±2%. Hipot levels are 3500 V primary to core and primary to primary, and 7000 V secondary to core and primary to secondary, 60 Hz for 1 second.
The core is B-0393 in a side-mount arrangement (Style 10), with a 1/2 in strap around both cores and the mounting bolts, and 0.500 in x 0.313 in mounting slots in 2 places. Leads exit 18 in minimum, stripped 0.5 in. Weight is approximately 23 lbs (shipping 23 lbs / 10.43 kg). Hipersil C-Core styles 8, 9 and 10 are quoted by the office, so confirm pricing and availability for PWDP13026 before ordering. REACH and RoHS compliant.
