Ordering Information
Product Specific Information Number (PSIN)
TPF-56 / nn
nn: Number of Current-sourcing, 20 milli-Amps Current-Limiting, Transistor
Output stages: 04,08, 12, or 16.
Please specify the “nn” while quoting, ordering, buying etc.
Note that the Is12 V DC Supply is from User Side, and the “Return” for
all Command Outputs of TPF-56/nn are “Commoned” to 0 V of the +12 V DC
Supply, at the TAS Thyristor Switches Side.
The TPF-56 Units with TAS Capacitor-Duty Thyristor Switches make ideal
combinations for Applications in Welding Shops, Reciprocating Piston Air-
Compressors, Electric Arc Furnaces, Induction Furnaces, Rolling-Mills etc.
