DN2R-100 Automatic Transfer Switch

1. Overview

1.1  Series dual power automatic transfer switches are newly developedminiature household power transfer switches. This switch is mainly used to test whether the normal or standby power supply is normal.

When the normal power supply is abnormal, the backup power supply will work immediately to ensure the continuity, reliability and safety ofthe power supply. This product is specially designed for home track TV installation and is specially used for Pz30 distribution box.

1.2  Series of automatic transfer switches are suitable for emergency power system 400v，60A with AC rated current of 50v or 60Hz compact structure , reliable conversion, easy installation and maintenance.long life.

lt is widely used in various occasions where continuous power failure is not allowed. lt can be operated electrically or manually by ATS, and the controller.DN2R-100

1.3  Complies with requirements of Low-voltage Switch Gear and Control Gearspecified by IEC 60947-6-1 and IEC60947-3: functional equipment and transfer switch equipment.

2  Product Model and Classification

3  Basic Parameters

See Table 1 for the basic parameters of Table 1

4  Normal working conditions and installation conditions

4.1  Ambient temperature: the upper limit does not exceed + 40°C. The average value of 24h does not exceed + 35℃, and the lower limit is not lower than -5℃.

4.2  The altitude is higher than the installation site and the altitude does not exceed 2000m.DN2R-100

4.3  When the highest atmospheric temperature is +40℃, the relative humidity of the atmosphere at the installation site should not exceed 50%.

At lower temperatures, higher relative humidity is allowed, for example,temperature +25C,relative humidity is 90%. Due to temperature changes, occasionally measures should be taken to prevent condensation on the surface of the product.

4.4  Pollution degree The pollution degree of TSE complies with the level 3specified by lEC.The installation category of 60947-6-1 and lEC 60947-34.5 installation category TSE conforms to the category specified by lEC60947-6-14.6.

Installation conditions can be installed vertically in acontrol cabinet or power distribution cabinet. Make sure: the installation distance S is as shown in the figure. 1 …

5  matters needing attention

5.1  Manual/automatic operation can ensure the on and off performance in electrical operation, but in manual operation, it cannot be guaranteed due to the difference in the operator’s on and off speed. In manual operation,excessive silver alloy loss may occur.

Therefore, only aftercutting off all power to check and maintain the operating system and contact information, can the selector switch be pulled to the manual position. Normally, please pull the selector switch to the electric position.

When manual operation is required, pull the selector switch to the manual position. After the manual operation is completed, pull the selector switch from the manual position to the automatic position.

5.2 The control circuit TSE is excited instantly. After the conversion is completed,the internal switch will damage the coil in the control circuit.

The coil can work normally at 85%-110% of the rated working voltage. Too low input voltage may cause the coil to heat up and burn.DN2R-100

6  Installation and wiring

6.1  Before installation and wirng, please ensure that professionals have read this manual.

6.2  Before installation, please check the integrity of the ATS. Then tum on the ATS with operating handle, check the fexibility of the operating mechanism, andcheck the on and off status of each phase and the load of the nomal and altemative power sources.

6.3 The nameplate of the product can be seen from the front. lf you fail to install inthe specifed direction due to wiring or other reasons, please contact us. The safety distance S1, S2 should not be less than the distance specified in Figure 2.(More infommation on side picture).

6.4  Check the control power supply voltage: 50 / 60Hz AC220V. The connecting wire of the control circuit should not be too long. The cross-sectional area of the copper wire should be greater than 2.0mm.DN2R-100

6.5  Please equip the ATS with suitable circuit breakers according to the installation requirements of the power distribution system to ensure the safety of personnel
and equipment.

7 Maintenance, inspection and storage

7.1 Maintenance and inspection should be performed by professionals Before cutting off all power supplies.

7.2 To ensure the good performance of the ATS, the first maintenance and inspection should be carried out within 6 months after use.

Then maintain and inspect at least once a year. Under severe installation conditions, the frequency of maintenance and inspection should be increased.

7.3 lf the maintenance and inspection items fail, please remove the dust. b.Please check whether the electrical contact parts are deformed and damaged,and remove the metal particles and scorch on the surface cand its surroundings.

Rust, acidification and dust on the contact surfacemay cause poor contact, so please perform several manual operationsand measure the necessary contact resistance.d.lf the ATS is damp or left empty for a long time, please dry it before turning on the power. After removing the dust, use a 500V megger to measure the insulation resistance of the normal power supply and AC power supply.

Load side and two poles, including insulation resistance, when using live parts and metal plates, the insulation resistance should not be less than 10MQ.

7.4  Amphetamine-type stimulants should be stored in the same environment as normal working conditions with dust, moisture and collision avoidance measures.DN2R-100
