Power generators' requirement for IRC 5 controller

sunyc

Hi,

We are looking at operating the IRC 5 controller (with IRB 4600) through a power generator (e.g. diesel or gasoline power generator) due to plant limitation of 3-phase fixed line power supply.

Based on the "Product specification - Controller IRC5", the voltage requirement is as follows:
1. 200-600 VAC (+10%, -15%), 3-phase, 48.5 - 61.8 Hz   OR
2. 220/230 VAC, (+10%, -15%), 1-phase, 48.5 - 61.8 Hz
with controller rated power of 13 kVA.

Question 1:
Based on the above listed voltage requirement, am I right to say that the current requirement for power generator could be calculated as follows:
1. For 3-phase, the current is approximately 22-65 A   (i.e. 13 kVA / 200 V,  13 kVA / 600 V) 
2. For 1-phase, the current is approximately 56-60 A   (i.e. 13 kVA / 220 V, 13 KVA / 230 V)

Question 2:
If my assumption in question 1 is valid, then line fusing of 25 A (for 400-600 V) or 35 A (200-220 V) seems to be lower than the current limit. Do I missed out something?

Question 3:
If we were to operate the IRC 5 controller through power generator, what are the requirement that we need to take note? (e.g. current limit, voltage and current stability, etc)

Appreciate your help and advice.
Thank you.

Hello 
Have you seen the product detail silver sticker on IRC5 controller. You can see correct required voltage requirement on it.
