Efficiency and losses

Efficiency for 3-phase operation:

		3AC 400 V	3AC 480 V
Efficiency	Typ.	95.3%	95.2%	At 24 V, 40 A
Average efficiency¹⁾	Typ.	94.7%	94.6%	25% at 10 A, 25% at 20 A, 25% at 30 A. 25% at 40 A
Losses	Typ.	1.5 W	1.5 W	If switch-off is activated
	Typ.	9.5 W	9.8 W	At 24 V, 0 A, (no load)
	Typ.	24.1 W	25.0 W	At 24 V, 20 A, (half load)
	Typ.	47.3 W	48.4 W	At 24 V, 40 A, (full load)

¹⁾ The average efficiency is based on assumptions for a typical application with a power supply load of
25% of the nominal load for 25% of the time,
50% of the nominal load for 25% of the time,
75% of the nominal load for 25% of the time and
100% of the nominal load during the remaining time.

Efficiency and losses 1: — Efficiency over output current; losses over output current

Efficiency and losses 2: — Efficiency over input voltage; losses over input voltage

		2AC 400 V	2AC 480 V
Efficiency	Typ.	94.4%	94.7%	At 24 V, 40 A
Losses	Typ.	56.9%	53.7%	At 24 V, 40 A (full load)

Efficiency and losses 4: — Efficiency over output current at 24 V; losses over output current at 24 V
