The TRIAD quick pack small power transformer series from MagneTek offers a
significant reduction in size and weight for a given VA rating. These
transformers are available in six sizes for a wide variety of applications. They
are bobbin wound for reduced size and small operating space. Split bobbin
nonconcentric winding eliminates costly electrostatic shielding. Termination is
suitable for quick connects or soldering.
Specifications. Primary:
115 V or
115/230 V, 50/60 Hz.
VA Range:
2.4 to 100.
Output Rating Range:
10 V CT to
48 V CT.

*CT = Center tap.
TRIAD chokes are manufactured in a wide variety of inductance values and physical configurations. Smoothing chokes are power supply filter chokes having a core
with an air gap which prevents saturation at maximum direct current.
Specifications. Inductance Ranges:
0.005 to 15 H.
DC Current Ranges:
10 Ma to 22.5 A.
Resistance Ranges:
0.06 to 3500 ohms.
