FUSING INFORMATION
• 1.5 kW front end: 7 A / 250 V normal blow in all
three phases of the AC line (Bussman ABC-7 or
Littlefuse 314-007).
• 3 kW front end: 12 A / 250 V normal blow in all
three phases of the AC line (Bussman ABC-12 or
Littlefuse 314-012).
• 5 kW front end: 20 A / 250 V normal blow in all
three phases of the AC line (Bussman ABC-20).
ENVIRONMENTAL DATA
• Operating temperature (no load to full load):
–20˚C to +50˚C, free convection
• Non operating temperature: –40˚C to +80˚C
• Operating / non-operating humidity:
95% relative, non-condensing
ELECTRICAL DATA — AC LINE INPUT VOLTAGE
CONNECTIONS (PHASE TO PHASE)
• 3-phase delta (4 wire): 208 Vac (nominal) +20% / –10%.
Connect the three phases (L1, L2, L3) and GND (earth)
to the five terminal barrier block marked as such.
• 3-phase wye distribution (5-wire): 208 Vac (nominal)
+20% / –10%. Connect the three phases (L1, L2, L3),
N (neutral), and GND (earth) to the five terminal barrier
block marked as such.
• Line frequency: 47 – 440 Hz
DC OUTPUT CONNECTIONS AND MODULE ENABLE
A three terminal barrier block labeled Vdc–, Vdc+ and
MOD EN provides both the DC input enable and enable
control line for Vicor converters.
• Vdc–: Negative DC input terminal to all Vicor converters.
• Vdc+: Positive DC input terminal to all Vicor converters.
• MOD EN: Connect to the GATE IN terminal of all Driver
modules. This connection must be made to guarantee
proper enabling of the converter array on power-up and
proper shut down of the converter array on power loss,
loss of phase or output fault.
CAUTIONS
