Regulated Heating Power Supply For Tubes 12.6 V - 1 A - Very Low Noise The description of this item has been automatically translated. If you have any questions, please feel free to contact us. Very compact, high efficiency resonant power supply module. Mains input 90 V - 260 V / 50 or 60 Hz, output 12.6 V - 1 A permanent load - 2 A peak. This module allows you to safely heat many tubes and does not produce any noise: ideal for RIAA, NAB corrector circuits or preamplifiers. - Light weight and bulk. - Very low heating. - No induction or radiation. - Direct current heating of the tubes: suppression of all 50 Hz noise or harmonics and simplification of ground circuits. - Precise adjustment of the output voltage between approximately 10 V and 14 V, which allows you to have exactly 12.6 V or other voltages across the filament. - Soft start of heating: no thermal shock on the filament. - Voltage regulation to within 0.01V regardless of the mains voltage (between 90 V and 260 V) and the load (1 A) This module replaces, in a very small volume, a heating transformer + a system rectification and regulation electronics. The connections are made very simply by 5 screw terminals: 2 "AC" terminals receive the mains, a “FG” terminal (Frame Ground) allows the shield to be connected to ground or earth and 2 output terminals "G": negative pole and "V": positive pole, deliver the heating voltage. The device is protected against electrical overloads, thermal overloads, short circuits and power surges. A mains filter is integrated. Overall dimensions: 78 x 48 x 20 mm, an ecc81 (12at7) gives the scale. max., automatic recovery Cooling: Natural convection Operating temperature: -10° to +40°C Mains input 90 V - 260 V / 50 or 60 Hz, output 12.6 V - 1 A permanent load - 2 A peak.
