Description

The 3B Scientific U33010-230 is a versatile, floating high-voltage source designed specifically for the operation of electron tubes. This unit provides a continuously adjustable high voltage output ranging from 0 to -5000 volts DC with a maximum current of 2 mA. To support electron tube functionality, it includes a built-in, high-voltage resistant transformer that supplies a 6.3 volt AC heater voltage at up to 3 amperes. Safety is integrated through passive current limitation and a digital voltage display for precise monitoring. This power supply is built for reliability in educational and scientific settings, featuring 4mm safety sockets and comprehensive overload protection via primary fuses and secondary current-limiting resistors.
