Features :

- Module power supply resonance, very compact, high-performance

- Input AC 90 V - 260 V / 50 or 60 Hz, 5 V - 4 A (20 W) continuous load -7 A peak

- Overall Dimensions: 95 x 58 x 25 mm (1 300 b triode giving wide tube - not part of the offer)

- Weight: 120 g

- Fixing by 2 screws (3 mm Integrated base threads)

- Heating DC tubes: no noise 50 Hz, simplification of mass circulation

- Fine-tuning the output voltage between 4.6 and 5.4 V minimum, which allows you to have exactly 5.0 V across the filament

- Soft start heating (soft-start): no heat shock filaments

 - Control voltage 0.01 V near whatever the supply voltage (90 to 260 V) and load (5 A max)

- Protected against power surges, thermal, short circuit and overload

- 1 integrated mains filter

- Input Specifications:

  Input voltage: 90-260 Vac

  AC Frequency: 47-63 Hz

  Power Factor:> 0.92

- Output characteristics:

  Adjustable tension between 4.6 and 5.4 V minimum

  Current: 4 A minimum

  Load Regulation: ± 1.0%

  Line Regulation: ± 0.5%

  Thermal drift: <0.03% / ° C (10-50 ° C)

  Start-up Time: 300 ms max @ 230 VAc

  Hold-up Time: 30 ms min, 100% Load @ 230 Vac

  Overload current: Load> 140% 90/260 Vac, automatic recovery

  Short Circuit: Protected for 30 sec max, automatic recovery

- Cooling: Natural convection

- Operating temperature: -10 ° to +40 ° C

 

Uses :

- Module can widely ensure the heating and DC voltage of thousands of controlled amplifiers - V lamps equipped preamplifiers 5 and directly heated as the triode 300 B (1.2 A per filament)

- Module replacement in a very small volume, transformer heating + system recovery and control electronics.

- Connections are performing very simply by 7 screw terminals: Terminal 2 "AC" receiving area, a terminal "FG" (Frame Ground) to connect the shielding to ground or earth and two output terminals "G "(negative pole) and" V "(positive pole) supplying the heating voltage

 

Specificities :

- Tube not part of the product sold

- Very low weight & dimensions

- Very low heat

- No induction or radiation
