Special regulator for elevators and cranes technical Parameters

Basic indicator

Protective function

Input voltage

380V ± 20% or wide voltage special definition

Overpressure

Output exceeds rated voltage by 10% (adjustable), delay 3-5 seconds to cut off output power

Output voltage

380V±5% selectable

Undervoltage

Output exceeds rated voltage -15% (adjustable), delay 3-5 seconds to cut off output power

Voltage regulation accuracy

1-5% can be set

Delay

2 seconds to cut off the output power

Frequency

50Hz/60Hz

Short circuit

Cut off the output power when the load device is shorted

Strain time

≤0.05s

Overcurrent

When the rated output current is exceeded, the output power is cut off after 3-5 seconds delay.

Stable schedule

When the input voltage changes by 10% relative to the rated value, the stability time is 1s.

Reverse phase

When an error occurs in the three-phase electrical phase sequence, the machine alarms and cuts off the output power (settable)

 

Missing phase

When there is a phase loss in the three-phase power, the machine alarms and cuts off the output power.

Bypass

Manual or automatic pass-through device for power supply failure or repair

Other indicators

Additional waveform distortion

≤0.1%

Withstand voltage

The whole machine has no breakdown and no arcing at 2000VAC/min.

Noise

55dB

Insulation resistance

Machine to ground2MΩ

Efficiency

More than 95% below 50KVA, more than 98% above 100KVA

EM filter device

Can effectively filter harmonic interference of the power grid (optional configuration)

Relative humidity

20%-90%

Lightning protection device

When the power grid changes instantaneously and inductive lightning strikes, it can protect against inrush current (optional configuration)

Way of working

Long-term continuous unattended work

Monitoring interface

With R232, RS485 interface, remote control, remote signaling, telemetry (optional configuration)

1. SBW-QZ series elevator, crane special regulator is EECTECH based on market experience, for elevators, lifting machinery and equipment host start and stop frequently, large inrush current, and users have high safety requirements for electricity, for the industry User-tailored, personalized, industry-specific voltage regulators. The special regulators for elevators and hoisting machinery have the characteristics of strong anti-overload and impact, high reliability, and long-term continuous circulation.

2. SBW-QZ series elevators and hoisting machinery special regulators are mainly used for elevator equipment in hotels, hotels, hospitals, business centers and other occasions where power supply conditions cannot meet the requirements; also applicable to mines, heavy machinery and other occasions. The lifting equipment is used for stable power supply.

3. The SBW-QZ series elevator and crane special regulators should be used indoors. The normal conditions of use are:
     1), ambient temperature: -10 ° C - +45 ° C
     2), altitude: <1000M
     3) Relative humidity: 20%-90%
     4) There are no gases, vapors, chemical deposits, dirt and other explosive and corrosive media that seriously affect the insulation of the regulator.
     5) There is no serious vibration or bumps in the installation site.
