Hi All my Friend 🙂

What is power supply part number AC-DC for ISA 3000 / ISA-3000-4C-K9 ?

what is power supply / converter AC-DC for ISA 3000 / ISA-3000-4C-K9 ?

Maximum DC input current
• 0.5A @ 48VDC
• 1.0A @ 24VDC
• 2.0A @ 12VDC

if using PWR-IE50W- AC-IEC= :
24VDC/2.1A
over ampere

PWR-IE65W- PC-AC=
54VDC/1.2 A
over volt and ampere.

Hi. It will be fine with PWR-IE50W-AC-IEC=.

The power supply in this case is voltage power supply, It should match the ammount of Volts supply and device . Current (amps) will be drained on demand as needed.

Power in watts (50 W in your case) is the result of:

24V*2.1A =~ 50W

ISA3000 uses 24V*1.0A=~24W you are just draining 24W from the power supply.

You can even use 24V /100A power supply and It'll be ok since the device will only drain the needed current. But you NEVER should use out of range voltage, you can damage device and power supply.

Best regards.

are you sure, higher ampere will not broken the device ?
i have looking many theory about high voltage and current, there is so many theory , make me confuse.

Hi, of course.
We have installed a lot of this firewalls before.
