Rated voltage is selectable between 220V and 380V, with a single-plate power of 1.5kW to 3kW. This range covers the single-phase and three-phase power supply conditions of most industrial sites. When checking the nameplate parameters, procurement personnel can compare the site's power distribution capacity, wire diameter, and circuit breaker specifications together to avoid situations where the power matches but the line's current-carrying capacity is insufficient.
The 220V model is suitable for single-phase power distribution occasions, while the 380V model is suitable for higher-power workstations with three-phase power supply. During selection, first confirm the available voltage at the site, then determine the power level according to the heating area and temperature rise requirements. It is not recommended to place an order based solely on the plate surface dimensions.
This type of electric heating plate adopts PID closed-loop control and is equipped with a Pt100 platinum resistance sensor, which can keep temperature fluctuations within a small range and reduce the plate surface temperature difference caused by frequent on-off switching. It is suitable for heating processes with certain requirements for temperature stability. For processes sensitive to temperature uniformity, it is recommended to specify the operating temperature range before procurement.
It is recommended to conduct a small-batch trial of 5 to 10 sets before the first purchase, recording the heating time, surface temperature uniformity, and operational stability, and then scale up the order after confirmation. The trial records can serve as a reference basis for subsequent batch acceptance.
Confirm that the rated voltage is consistent with the site power supply; check that the power matches the power distribution capacity and wire diameter; clarify the temperature control method and sensor configuration; agree on the plate surface material and installation method; retain the heating and uniformity data from the trial stage.
Terminal protection, lead wire specifications, and mounting hole positions are customized items. They should be confirmed with drawings before ordering to avoid mismatch with equipment interfaces upon arrival.
