Hammond Transformers Model 193L (193 Series)
D.C. Filter Choke - 5 H, 300 ma, 57 Ohms, 800 Volts D.C.
This enclosed common mode D.C. filter choke is perfect for high voltage power supply filtering. Its case matches power transformers & tube audio output transformers. The units are vacuum impregnated with polyurethane varnish for quiet and long-life operation.
Proper Henry testing requires an LCR meter in junction with a 25A power supply that does allow for DC bias as well a higher applied AC drive voltage to meet the test specifications.
Features:
- Enclosed, 4-hole mount chokes
- Tolerance of 15% on both inductance & resistance.
- Inductances measured at rated D.C. current.
- Minimum 8" long leads.
- Units will exhibit less inductance at slightly higher currents or more at lower currents.
- Perfect for high voltage power supply filtering, case matches power transformers & tube audio output transformers.
- Units are vacuum impregnated with polyurethane varnish for quiet and long-life operation.
- Operating temperature range is -40C to 65C
- Insulation class 105C
- Proper Henry testing requires an LCR meter in junction with a 25A power supply that does allow for DC bias as well a higher applied AC drive voltage to meet the test specifications.
