3. Potting Compound PC3502 E135297(M)

Mechanical Specification

1. Middle of transformer to be potted. Potting to be drilled out with an 6mm DIA Hole

and then the bottom surface counterbored to a depth of 12mm with a 12mm dia drill
as shown. Actual part which the counterbore is designed to clear extends up to 10mm from
transformer mounting surface into counterbore.

3. Use 24 AWG wire with colours as shown. Primary wires are enclosed in a common

sleeve. Secondary wires are enclosed in a common screen. Use PVC sleeving.

4. All wire lengths in mm. Lengths are +5.0, -0

5. Please adhere rubber insulating pad to bottom of transformer as shown.

Electrical Specification

1. Transformer to have dual 100V primaries to allow parallel operation for

100V input.

2. Transformer input voltage range

100V -18% +14% (82V to 114V)

3. Transformer to have two secondary windings as show in the adjacent drawing.

4. Loaded DC voltages specified at 100V AC in (with transformer primaries in parallel)

DC supplies to be generated by configuring the seconday windings with a full wave bridge
(see diagram).
Output Capacitance to be 3300uF. 22V dc
Output Capacitance to be 1000uF. 9.5V dc

VOUT1 = 22.0V dc @ Io = 250mA (With 100V AC in)
V0UT2 = 9.5V dc @ Io = 150mA (With 100V AC in)

(this will ensure that VOUT2 is 8V at 82V AC in)
