p

  • Grade 4 Class S Construction
  • Hermetically sealed, rugged MIL-PRF-27 transformers
  • Standard output voltages: 5 to 486 volts
  • Threaded inserts for versatile mounting
  • Wide range of power ratings: 5, 10, 15, 20, 30, 40, 80,120, 160, 200, and 300 VA

Input Primary:
115 V ac, 60 Hz +5 Hz**, 1 phase.

“A” Option: 230 V ac. Add suffix “A” to model number, e.g., 5P10CTA (Fig. 1).

“B” Option: 115/230 V ac. Add suffix “B” to model number, e.g., 5P10CTB (Fig. 2).

**For 50 Hz operation, reduce secondary current by 10% of listed ratings (These units are capable of 400 Hz operation.)

Regulation:
12% or less no load to full load (Sizes A1-A2) 10% or less no load to full load (Sizes A3-A11).

Secondary Voltage Tolerance:
Within 3% of listed output voltage when measured at full load and listed input.

Dielectric Withstanding Voltage:
1750 V ac.

Efficiency:
Ranges from 80% to 90% typical.

Operating Ambient Temperature:
95° C maximum.

Construction:
To MIL-PRF-27, Grade 4, Class S; steel case.

Environment:
Encapsulated to meet MIL-STD-810 for vibration, shock, acceleration, sand, dust, humidity, saltspray, fungus, sunshine, rain, explosion, and altitude. NOTE: For high altitude operation, encapsulate terminals.

Output Secondary:
See output voltage and current of specific models listed.

Other outputs and/or inputs available upon request.
