Double Transfer Switch With Automatic Changeover For Municipal Electricity, Ups,

Specification: Item Type: Dual Power Automatic Transfer Switch Product Model: NLQ4-125/4P Switch Type: Secondary power distribution Rated Current: 100A Rated Voltage: 400V AC Insulation Voltage: 690V AC Rated Frequency: 50Hz/60Hz Electrical Grade: PC grade isolation type Service Life: Electrical: 2000 Times; Mechanical: 5000 Times Rated Short Circuit Current: 50kA SCPD (fuse): RT16-00-63A Rated Impulse Withstand Voltage: 8kV Control Circuit: Rated Control Voltage Us: AC220 V 50Hz Normal Working Condition: 85% Us-110% Us Auxiliary Circuit: 2 Independent relays, each relay includes 2 sets of transformer contacts Contact Capacity: AC220V 50Hz Touch Time: <50ms Operation Transition Time: <50ms Return Time: <50ms Off Time: <50ms Package List: 1 x Dual Power Automatic Transfer Switch Note: 1. The maximum ambient temperature should not exceed 40℃, the minimum should not be lower than ‑5℃, and the average temperature within 24 hours should not be higher than 35℃. 2. The altitude of the installation site should not be higher than 2000meter. 3. When the maximum temperature reaches 40℃, the relative humidity of the installation site should not exceed 50%; when the temperature is the lowest temperature of ‑5℃, the relative humidity is higher, for example, if the temperature is 25℃, the relative humidity is 90%. Special measures should be taken to deal with occasional condensation on product surfaces due to temperature changes. 4. During conversion, the internal switch will lose the coil in the control circuit. The coil can work normally at 85%‑110% of the rated working voltage. If the voltage in the coil is too low, it may cause the coil to heat up or burn out.

Product Features

  • SCOPE OF STANDBY POWER SUPPLY APPLICATION: This product is a photovoltaic version of the dual power supply automatic transfer switch, unlike the municipal power product can only be applied to the utility or generator, this product can be applied to UPS, inverter, solar, photovoltaic as a standby -Power supply can be connected. The product has passed CE certification and can be used with confidence.
  • INSTALLATION SIZE: The dual power transfer switch adopts 35mm DIN rail installation design and comes with a buckle. The height of this switch is 76mm, which may not be suitable for some standard rail installation junction box. Please pay attention to the size of the junction box before purchasing, to avoid the junction box cannot be closed normally.
  • FAST SWITCHING: The switch switching response time is ≤0.05(S), and the power supply is switched in milliseconds to ensure the continuity, reliability and safety of the power supply. Note that automatic switching is only possible when the emergency power supply is already on, manual switching is required if the backup power supply is not on.
  • TECHNICAL PARAMETERS: The cross-sectional area of the connectable cable: ≤16mm²; Rated control voltage Us: AC220 V 50Hz; Rated current: 100A; Rated voltage: 400V AC; Insulation voltage: 690V AC; Rated frequency: 50Hz/60Hz; Rated short-circuit current: 50kA; Rated surge voltage: 8kV; Service life: electric: 2000 times; mechanical: 5000 times.
  • FLAME RETARDANT MATERIAL: made of high quality flame retardant plastic, with good insulation, high temperature resistance, aging resistance, safe and reliable. The use of silver contacts can greatly improve the conductivity and service life of the product.
