Transformer - Isolation, 35 VA, 115V, 300 mA, 1 x 115V
35VA chassis mount Power Transformer for isolating equipment from direct connection to the power line. It is constructed with non-concentrically wound coils. The primary and secondary are wound on separate arbors, then assembled on a laminate core side-by-side separated by insulation. This prevents electrical connection under normal or overload conditions between the primary and secondary windings. These units are designed with 1500V isolation between winding to winding and between winding and core. Materials and construction are rated for Class B insulation system.

Transformer - Hammond, 145 Series, Audio Chassis Mount
Features:
  • Small, economical, open, two hole horizontal bracket mount.
  • Insulated, color coded flexible leads, 4" long minimum
  • Frequency response 150 Hz. to 15 Khz. (+/- 1 db, reference 1000 Hz.)
  • When operating at impedances below nominal, power capability and the frequency spectrum are proportionately lower, conversely, at higher impedances power capability and frequency spectrum will be proportionately higher.

Transformer - Hammond, Plate & Filament
  • Universal primary with taps for 100, 120, 220 or 240 VAC, 50 / 60 Hz. (Except the 260A6 which is 117V, 50/60 Hz only)
  • Designed for preamps, low power amps, general replacement, test equipment, etc.
  • Economical, open frame, chassis mount - two hole (.187 dia. = G) channel bracket (figure #1) or four hole mounting (figure #2).
  • Units include a Faraday shield between the primary and secondary windings. Our electrostatic shield reduces the capacitive coupling from the primary - greatly attenuating higher frequency current coupling to the secondaries.
  • Minimum 5" long leads.
  • For more selection check out our P-T300-X series of universal plate & filament transformers.
