The attractive 70000-series PC Mount toroidal step-down transformers
offers the design engineer the same features as our non-encapsulated
toroidal power transformers, namely, very low EMR (magnetic stray-
fields), quiet operation, low temperature rise, low profile, low no-load
current and very low no-load losses.
STANDARD FEATURES
• Primary voltage of 115V or 230V at 50 / 60Hz.
• Safety standard certifications (UL 506, UL 1950
(UL File #E145880), VDE 0805, IEC 950, EN 60950.
• UL File #122978 recognized for insulation Class A (105C).
Meets all requirements of Class E (125C)
• UL and VDE certifications to +40°C (1.6VA-25VA)
• Hipot testing at 4000V between primary and secondary.
( VDE0550)
• Maximum ambient temperature of +60°C for 1.6VA- 25VA,
+40°C for 35VA and 50VA models
CUSTOM DESIGN OPTIONS
With minimum order of 1000 pieces custom specified primary and
secondary voltages are available.
Please contact the Houston factory or your local Amveco sales
representative for details.
WIRE DIAGRAM AND TERMINAL PIN LAYOUT
NOTES
For 230 volt operation, connect primaries in series by connecting pins 5 & 4
together and apply 230 volts across pins 6 & 3.
For 115 volt operation, connect primaries in parallel by connecting pins 6 &
4 together and pins 5 & 3 together; apply 115 volts across pins 6 & 5.
To parallel the secondaries, connect pins 14 to 12 and 13 to 11; take the out-
put across pins 14 and 13.
To place the secondaries in series, connect pins 13 to 12 and take the output
across pins 14 and 11.
Minimum order quantity is 500 pieces per part number. For less than 500
pieces, please contact our distributor Digi-Key Corporation at 800-344-4539
or order on line at www.digikey.com.
