5. Usage:
5.1 About Power Supply: ultrasonic control system and power supply separately screening test, test sieve and ultrasonic power are single-phase power supply.
5.2 Host and ultrasonic vibration power connection: The T200 test sieve box type oscillator connection line ultrasonic vibration power plug socket behind, open the power supply ultrasonic vibration start work, according to screening is necessary to readjust the power knob.
5.3 DH-300 test sieve of steps: First, test sieve type T200 test box placed on sieve tray fixture height adjustment, tighten nut M12 and M8, and then plug the power cord 220V socket, according to testing requirements of regulation time the timer, open the Screen test start switch job, time zero countdown timer automatically turn off when the host.
6, ultrasonic vibrations power features:
6.1 seamlessly continued unique circuit, performance is more superior. (This is my unique domestic counterparts in the latest technology)
6.2 automatically track the frequency of really functions: automatically track the output inductor and the first resonant frequency of vibration, vibration effects will not be as temperature, humidity, and the use of oscillator aging time conditions change, so that the vibration effects have been maintained at the highest level, frequency deviation only 0.1 ‰, conversion efficiency ≥ 92%.
6.3 output current for pure spin waves, can be extended oscillator and signal generator's own life.
6.4 Automatic Sweep functions: sweep frequency from 10HZ-2KHz adjustable sweep power from 10% -100%, so that vibration better. (Change can produce multiple harmonic)
6.5 output current ripple ≤ 1%, so that the vibration effect of a more stable, good protection from damage oscillator.
6.6 the use of closed-loop control, the output current is more stable, so that current will not be with the input voltage, oscillator aging and other conditions change, can be sustained to maintain a strong power. (Many products on the market for open-loop control circuit, that is to say only see the front of the current, before and after should not very good communication, resulting in inconsistency)
6.7 Input power adjustable.
6.8 input current shows that the frequency of follow-up instructions, instructions have been the temperature, output short-circuit the instructions, the first vibration failure instructions. Could have been more intuitive understanding of their job status (intelligent type equipment).
6.9 protection function: over-power protection, overcurrent protection, overvoltage protection, undervoltage protection, frequency tracking fail-safe, over-temperature protection, output short circuit protection, under different conditions at both the signal generator and vibrator to protect and extend the entire machine working life. (you can play the role of segregation, when the vibrator damage will not cause generator damage at the same time, same reason the other hand, happen when a short circuit can automatically adapt to not damage the machine)
6.10 boot to prevent the impact of circuit, soft start to prevent the vibration head is too large instantaneous power damage. (To prevent transient current boot suddenly become larger, damaged circuit).
