Building an Isolation Transformer

[cdmarion]

Hey Guys,

I want to build an isolation transformer to protect myself from some of the AC/DC sets i'm working on and have a question.

I understand how to build an IT using two similar transformers. But i just found this IT from WWW.Mouser.com part# 553-N51X. Here is some info from the data sheet,



[QUOTE][Electrical Specifications (@25°C) 1. Maximum Power: 35 VA 2. Input Voltage: 115 V, 50 / 60 Hz 3. Output Voltage: 115V + 5% 4. Full Secondary Load: 0.30 Amps RMS 5. Voltage Regulation: 15 % TYP @ full load to no load
Description: The N-51X is power transformer for isolating equipment from direct connection to the power line. It is constructed with nonconcentrically wound coils. The primary and secondary are wound on separate arbors, then assembled on a laminate core side-by-side separated by insulation. This prevents electrical connection under normal or overload conditions between the primary and secondary windings. WHTBLKBLKAREDRED.187 DIA (REF)2 HOLESDB Safety: These units are designed with 1500V isolation between winding to winding and between winding and core. Materials and construction are rated for Class B insulation system./QUOTE]

If i understand this rite i can use a single IT like the N-51X above instead of a pair of power transformers to build an IT. Am i on the rite track or do i need a pair of these also? Any thoughts or opinions?
