The 170D is a 500VA hard wired autotransformer for panel builders, electricians and OEM engineers who need to change line voltage between 115VAC and 230VAC. It works in either direction: step down from 230VAC to 115VAC, or step up from 115VAC to 230VAC, at 50 or 60 Hz, which makes it suited to flexible worldwide applications.
Because it uses a single winding, the 170D does not provide isolation. It is intended for use where the equipment is already isolated and only a voltage change is required. It also does not convert line frequency, so equipment that depends on 50 Hz or 60 Hz must still match the local supply.
Connection is by flexible leads with an 8" minimum length, so the unit is wired directly into the installation rather than plugged in. Overall dimensions are A 3.75 in (95 mm), B 4.50 in (114 mm), C 4.60 in (117 mm), D 3.00 in (76 mm) and E 3.30 in (84 mm). It is CSA certified (209651). This is the largest model in the 170 range that carries CSA certification (file 209651), alongside the smaller 170A, 170B and 170C.
The part is listed as RoHS compliant and REACH compliant, and is classified under UNSPSC 39121301 with UPC 623980249308. Shipping weight is 10 lbs (4.54 kg).
Ideal For
- Step-down from 230VAC to 115VAC for already-isolated equipment
- Step-up from 115VAC to 230VAC
- Voltage change for worldwide 50/60 Hz applications
- Hard-wired voltage conversion inside equipment or panels

Frequently Asked Questions
Can the 170D both step voltage up and down?▾
Yes. The 170D steps down from 230VAC to 115VAC or steps up from 115VAC to 230VAC, at 50 or 60 Hz.
Does the 170D isolate the load from the supply?▾
No. It is a single-winding autotransformer that does not provide isolation; it is for use where the equipment is already isolated and only a voltage change is required.
Will the 170D convert 50 Hz to 60 Hz?▾
No. These units do not convert line frequency; the output frequency is the same as the supply.
How is the 170D connected?▾
It is hard wired, with connection by flexible leads of 8" minimum length.
What are the dimensions and weight of the 170D?▾
Overall dimensions are A 3.75 in (95 mm), B 4.50 in (114 mm), C 4.60 in (117 mm), D 3.00 in (76 mm) and E 3.30 in (84 mm). Shipping weight is 10 lbs (4.54 kg).
Is the 170D CSA certified?▾
Yes. Models 170A, 170B, 170C and 170D are CSA certified (209651).
