FIELD: food industry; chemical industry.
SUBSTANCE: device can be used for packing filling products into polyethylene bags. Device has power supply made in form of energy scale having phase control. Rectifier bridge is introduced into device and transistor power scale is used, which is made in form of transistor switch, for example. Accuracy of keeping to specific (chosen) value of power at heater is provided, including cases when non-repeating distortions of network voltage's shape are present.
EFFECT: improved stability of temperature of heater.
