Autonics AT8SDN Star Delta Timer

Product Information

Model: AT8SDN
Product Name: Star-Delta Timer
Function: The AT8SDN Star-Delta Timer is designed to control the switching between star and delta configurations in motor control circuits. It offers a control time setting range of 0.5 seconds to 100 seconds.
Power Supply: The timer can be powered by a universal power supply, accepting a voltage range of 100-240VAC at 50/60Hz or 24-240VDC.
Power Consumption: The power consumption of the timer is 3.2VA for a 100-240VAC power supply and 1.5W for 24-240VDC power supply.
Control Output: The timer has two control outputs, both with single-pole single-throw (SPST) contacts capable of handling a 250VAC 5A resistive load. The mechanical cycle life of the contacts is a minimum of 10,000,000 times, and the electrical cycle life is a minimum of 100,000 times for a 250VAC 5A resistive load.
Repeat Error: The timer has a repeat error within the specified control time setting range.
Setting Error: The timer has a setting error within the specified control time setting range.
Voltage Error: The timer has an allowable voltage range of 90-110% of the rated voltage.
Temperature Error: The timer has a temperature error within the specified operating temperature range.
Switching Time Error: The timer has a switching time error within the specified control time setting range.
Insulation Resistance: The insulation resistance of the timer is 100MΩ at 500VDC using a megger.
Dielectric Strength: The timer has a dielectric strength of 2000VAC at 50/60Hz for 1 minute.
Noise Strength: The noise strength of the timer is…

Over-Heating Protection

The overheat protection function cuts off the output voltage when the temperature in an element increases due to overheating.
This product has an overheat protection function within itself.
When the overheat protection function is activated and the product does not work properly, please resupply power.

Cautions during Use

Follow instructions in ‘Cautions during Use’. Otherwise, it may cause unexpected accidents.
Do not connect the output voltage either in serial nor in parallel.
Since there is no harmonic suppression or power factor correction circuit, install the circuit separately if necessary.
Since using the condenser input method, the power factor is in the range of 0.4 to 0.6. When using a distribution board or transformer, check the capacity of the input voltage.
Even though a noise filter is installed inside the product, the product can be affected by noise depending on the installation location or wiring
If the internal fuse is damaged, please contact our A/S center.
In the case of models using the user-switching method for the input voltage selection, the factory default is set to 220V. When switching over to 110V, remove the case of the product as below and select the voltage with the jumper switch within the range of the input voltage.
To ensure the reliability of the product, install the product on the panel or metal surface.
Install the unit in a well-ventilated place.
Do not use near the equipment that generates strong magnetic force or high-frequency noise.
This unit may be used in the following environments.
- ①Indoors (in the environment condition rated in ‘Specifications’)
- ②Altitude max. 2,000m
