The main function of DTP500 series products

◆Has the start overtime protection, overload protection, broken phase protection, grounding protection, over-current plugging turn protection, current imbalance protection, short circuit protection, and increased leakage protection type explosive-proof motor overheating, carrying full protection (tE time protecting), owe load protection, temperature protection, voltage protection, over-voltage protection, owe power factor protection, such as the protection of sequence of digital protection function.

◆Accurate overheating protection digital models from eye principle solved motor thermal protection problems.

◆Te time protection accord with relevant increase Ann type explosion-proof motors overload protection regulations (GB3836.3-2000)

◆Realize the three-phase motor loop three, grounding/leakage current, current imbalance rate, three-phase line voltage, frequency and power factor, active power, reactive power, meritorious electric degrees and so on many kinds of electricity parameter measurement.

◆Meet directly startup, two-way startup, star/triangle startup, since the start of decoupling transformer start-up manner.

◆Controller this lift up 11 road switch input for start-stop signals, reset signal and contactor status signal input.

◆Controller provides no.5 relay output used for various start-up mode control, provide the number four programmable relay output.

◆Can provide 1 road to DCS 4 ~ 20mA analog output.

◆8 times fault record

◆Supported Modbus or Profibus communications bus.

◆Resistance to sway electricity function 10s, guarantee the sustainable power electrical phenomena does not affect the short-time sway the continuity of production process.

◆Owe pressure heavy start function in electric machine Lord circuit after short outage according to the parameter Settings realize time delay activated.

◆Support nine kinds of operation mode: protection mode, direct start-up mode, two-way reversible start-up mode, star/triangle start two relays mode, star/triangle startup three relays open-loop mode, star/triangle startup three relays closed-loop mode, self coupling transformer start two relays mode, self coupling transformer startup three relays open-loop mode, self coupling transformer startup three relays closed-loop mode. Operation mode Settings can be extended module or communication software Settings.

◆Motor provides the segmented protection, points the start-up process and operation process to motor to protect. During the start-up process protection, broken into start overtime in protection, current imbalance protection, grounding/leakage protection, short circuit protection, tE time protection function, after the start-up process other ecoenvironrnental protection.

◆Optional display module, can offer various site modify functions.

◆1B on-site can display 1A, 10, fever, 1C, state equivalence.
