1. Multiple LED indicator lights on the panel display the working status and fault causes of the voltage regulator controller, which is convenient for timely maintenance in case of fault.
2. The PC board adopts SMD chip, which has good anti-interference and low failure rate.
3. Slow start function is included to make the components more durable.
4. Proportional linear output, accurate temperature control, accuracy of 0.3%, meet the requirements of various loads.
5. The whole machine adopts aluminum alloy shell, small size, good heat dissipation effect, 100% guide fan airflow heat dissipation.
6. Input mode: 4-20mA, 1-5vdc and 2-10vdc, which can be freely switched by P1 jump without replacing the host.
7. All series of built-in fast fuse and overheat stop output protection switch protect voltage regulator controller and load.
8. Working conditions:
Ambient temperature: - 20 ～ 65 ℃
Relative temperature: 15-75% RH, no water condensation
Altitude: lower than 1000m, higher than 1000m, reduced according to GT / t3859.1-2013 (5.3) standard
9. The input power supply voltage of AC1 and ac2 terminals of PC board is 200-240Vac.
10. There is no phase sequence relationship between the main power supply and the working voltage of PC board, so it is easy to use (automatic identification of 50 hz-60 Hz).
11. The air convection hole and cooling fan must be installed in the closed control box. If the heat dissipation is poor, please reduce the power to use, No
It will cause the overheat protection function of the voltage regulator to start and stop output.
12. Please check whether the fan works normally from time to time. If not, remove the fan fault before putting it into operation
