Overview: Electrical and electronic skills training and assessment station

This product is based on improvement and innovation, and increases school skills training experiments. The DC stabilized power supply is extended to 0-30V, and the selected current interception protection is adopted: the frequency range of the signal source is expanded to: 0.2Hz ~ 2MHz, six-digit digital display; the output waveform of the signal source: sine wave, triangular wave, rectangular wave, positive and negative There are eight types of medium wave, positive and negative slope wave, and TTL square wave. A digital frequency meter is added to measure the frequency internally and externally. The low-voltage AC and DC power supply range is adjusted by precision switches.
Function and structure
Power supply: Three-phase four-wire 380V output (with fuse and leakage protection secondary protection function). A group of AC and DC power supplies are continuously adjustable from 0 to 240V; a group of AC currents are adjustable from 3 to 24V steps; a group of 5V DC regulated power supplies. The two sets of DC stabilized power supplies are continuously adjustable from 0-30v and are provided with cut-off overload protection. 0-60V continuous adjustable power can be obtained by connecting two sets of power in series.
Frequency meter: 6 digits display, can measure the frequency inside and outside, measuring range: 1Hz-100MHz.
Signal source: Output sine wave, triangle wave, rectangular wave, positive pulse wave, negative pulse wave, positive ramp wave, negative ramp wave, TTL square wave.
Frequency range: 0.2Hz-2MHz continuously adjustable in 7 steps, 6 digits display. ( Teaching Equipment | Teaching Instruments )
