MADELL QK870

Product catalog summary

Specification:
The MADELL QK870 is a pre-heat/reflow hot plate with an 800W heating power and a plate area of 180mm x 200mm. It features an aluminum plate material, a K Type Thermocouple temperature sensor, and operates within a temperature range of 50℃ to 300℃. The device maintains a temperature stability of ±2℃ and functions optimally in ambient temperatures of 0 to 40℃. Its outer dimensions are 280mm (W) x 290mm (L) x 100mm (H), and it weighs 5kg.

Features:
The hot plate ensures even temperature distribution and utilizes CPU closed-loop temperature control with a digital display. It includes zero voltage heater switching, dedicated power and heating switches, and is ESD safe. The device allows for external temperature calibration and features a hinged hood for creating an oven-like environment. It offers two heating states: pre-heating and reflow.

Operation:
To operate, plug in the power cable and turn on the power switch. The pre-heat plate temperature is displayed after the set temperature is shown for 2 seconds. Adjust the temperature using the arrow keys and turn on the heating switch to start heating. The device can be used as a pre-heat plate or a mini reflow oven. After use, turn off the heating and power switches. Caution is advised due to high temperatures.

Temperature Setting and Adjustment:
Temperature can be set regularly by turning off the heating switch and using the ‘*’ key to enter temperature setting mode. Adjust the digits using the arrow keys and save the desired temperature. During heating, temperature can be adjusted quickly using the arrow keys without pressing the ‘*’ key. The temperature increases or decreases by 1℃ with each press.

Parts List:
The parts list includes various components such as screws, reflow cover, fuses, grounding, power cord, top cover, support column, heating accessories, pad loop, screw nut, bottom holder, transformers, power socket, P.W.B, power cover, switches, temperature extrude plate, rubber pad, bottom plate, and waterproof connector.

3. Operation: • Plug the power cable. • Turn on the power switch. • Pre-heat plate temperature will be displayed after the set temperature is displayed for 2 seconds. • Adjust the up or down arrow keys to change the set temperature (see temperature adjustment). • Turn on the heating switch, the unit starts heating. It will reach the set temperature in a few minutes. • The unit may be used as a pre-heat plate when the cover is moved back or as a mini reflow oven when the cover is over the plate. • Turn off the heating switch after a circuit board is done. • Turn off the power switch at the end...

Notes: if power is off during temperature setting, the new temperature will not be saved. • If the “*” key is pressed less than 1 second, the set temperature will be displayed for 2 seconds. Display will be automatically switched back to pre-heat plate temperature. • • After the ‘*’ is pressed, power supply to heating elements will be out off. If an invalid temperature is entered, the 100th digit will flash, indicating a valid temperature is needed. (b). Temperature Setting during Heating If it is necessary to change plate temperature quickly while power supply to heat element is still maintained,...
