Precautions in Handling PS-24 Power Supply is a power supply unit dedicated for IAI controllers which utilizes 24V DC as a power source. There are 2 types, 100V AC and 200V AC specifications, for the input power. Even when lack of the power capacity is occurred, this power supply does not need to be replaced with another power supply with a bigger capacity. Another unit of this product can be added to the connection to perform a parallel operation. 5 units maximum can be connected.

RDY Display and RDY Output Signal".] 4) 5) +24V output terminal * 4) and 5) are connected internally.
10) AC input terminal (for 100V AC) Input terminal for 100V AC type. Note : Do not connect the unit to a power source that is not specified. 11) AC input terminal (for 200V AC) Input terminal for 200V AC type. Note : Do not connect the unit to a power source that is not specified. (Note) Connect the power supply as follows; for 100V AC input specification, 9) and 10), and for 200V AC input specification, 9) and 11). They cannot be used in common for each specification.
2. RDY Display and RDY Output Signal In a normal operation, RDY display should be illuminated and RDY output signal should be turned ON (electrically conducted). In case this RDY display is not illuminated and RDY output signal is turned OFF, lower the load or add another unit of this power supply. Take note that there are also other considerable causes that the RDY display light and RDY output signal are OFF as listed below.

Both methods A (standard) and B below are available as a mounting method, however, the characteristics for the output current relevant to the temperature will differ for each way. Use within the range of its characteristics for each method. Mounting Surface Output Current (%) Method A (Standard) Method B 110 100 90 80 70 60 50 40 30 20 10 0 A (Standard) B 0 10 20 30 40 50 60 Ambient Temp.
8. Output Voltage This power supply is able to be used in a parallel operation, and the output voltage fluctuates within the range of 24V±10% even in a normal operation. The voltage is set to around 25.8V at no duty. This voltage fluctuation does not influence the operation of IAI 24V controller at all. This power supply changes the voltage within the area between the solid line and the broken line below in response to the load. Output Voltage Fluctuation in accordance with Duty 26.
9. Protective Functions There are 4 patterns of circuits prepared as a protection function. (1) Over Current Protection Circuit The voltage suddenly drops when the current more than the rated value is output (includes short circuit). Power output automatically recovers when the over current condition is cancelled. There is a case that the over current protection circuit works due to the in-rush current caused by turning ON multiple controllers at the same time.
10. Parallel Operation Parallel operation is available under the following conditions. Parallel operation is allowed up to 5 units. Do not connect a different type power supply unit from PS-24 Power Supply in parallel. 2 terminals for each of positive side and negative side as the output terminals are provided. Use one terminal for the parallel connection, and the other for the connection to the load.
11. Simple Troubleshooting Contents Voltage does not output. Output voltage is low. RDY display does not illuminate. 21 Treatment Is the connected input voltage within the specification? Any short circuit or grounding fault on the output circuit? Time delay too short after over voltage or over temp protection activated.
