Product name: 30 kw panel

30 kw

A, the product electrical specifications:

1, frequency of rated voltage: 380 vac 50 hz / 60 hz

2, voltage range: 300 v to 450 v

3, power rating: according to the workpiece heating requirements

4, working frequency: 14-28 KHZ best period of 15-22 KHZ

5, safe working environment temperature: - 20 ℃ - 45 ℃;

6, work humidity: 95% or less

7, thermal efficiency is 95% or higher

8, wiring diagram

9 and the distance between coil and the heated body is 15 to 25 mm.

Second, the basic summary of performance.

1, soft start function, in the case of frequent start, safe and reliable, long service life

2, open phase protection function

3, with IGBT over-current protection function

4, IGBT overheat protection function

5, a heating coil short circuit protection function

6, the whole bridge series resonant circuit topology, strong anti-jamming capability

7, using high-performance IGBT driver chip driver

8, automatic identification load and phase lock function, in order to make the power factor of the load end, also make the accurate control circuit in low sensibility area high efficiency work

9, the number of movement on the same heating pipe installed in parallel, each other

10, good power saving effect: compared with the currently used electric heating circle, power saving can reach more than 30%

11, easy installation, can be bucket peace pans and so on induction coil structure way

12, low running cost, less maintenance, product 1 year warranty, life-long maintenance

Three, product use connect a load characteristic: 5130 # steel and 45 steel class, 1.5 3 cm distance between the coil and workpiece (special materials to special debugging)

1, 30 kw tubing steel are about 280-330 - uH, iron, 300-350, uH, induction coil wire diameter not less than 16 square millimeter (probably around 52 rice noodle)

Note: inductance just used one of the parameters, specific to the measured frequency and current work, through the increase or decrease in the coil number of turns to match the power, high heating temperature requirements are appropriate reduced, working frequency in 12 to 28 KHZ range, keep high temperature heated to the required frequency of not less than 13 KHZ (artifacts equivalent series impedance R at higher temperatures rise, RLC resonant frequency decreases, the same R, under the condition of invariable busbar voltage current decline is normal)
