48 V; 3.3 VDC models:
48 V; other models:
400 mA typ.
500 mA typ..
200 mA typ.
250 mA typ.
Start-up voltage / under voltage lockout
24 V models: 9 VDC / 8.5 VDC (or lower)
(hysteresis for assertive on)
48 V models: 18 VDC / 17 VDC (or lower)
(long term operation at undervoltage will
demage the converter!)
Surge voltage (1 sec. max.)

24 Vin models: 50 V max.
48 Vin models: 100 V max.
Conducted noise (input) EN 55022 class A, FCC part 15, level A
without external components
Recommended input fuse (slow blow)

24 V models: 2000 mA
48 V models: 1000 mA
Output Specifications
Voltage set accuracy ±2 %
Regulation
– Input variation (Vmin – Vmax) 1.0 % max.
– Load variation
single output models: 1.2 % max. (15 – 100 % load)
dual output models: 2.0 % max. (15 – 100 % balanced load)
Minimum load 15 % of rated max. current (operation at lower
load condition will not damage the converters.
However, they may not meet all listed specifications)
