AN450

Product catalog summary

Device Features
The AN450 is a power supply unit designed for Bender devices, providing AC 20 V with a maximum power consumption of 9 VA. It can supply up to three MK2430 alarm indicator and test combinations. The unit includes a protected secondary circuit.

Product Description
The AN450 supplies Bender devices with AC 20 V and supports a total power consumption of up to 9 VA. It can connect to a maximum of three MK2430 units. The supply voltage is connected via terminals A1/A2, and output voltage is available at U2/V2. Multiple AN450 units can be connected in parallel. The secondary circuit is protected by a PTC resistor.

Function
The unit features two input and output terminals for parallel connections. Ensure terminals A1/A2 and U2/V2 are not interchanged. Voltage loss in the line affects the number of devices that can be connected. For long cables, verify the supply voltage at the device terminals.

Standards
The AN450 complies with IEC 61558-2-6 standards.
