ProX 500 TRANSFORMER REQUIREMENTS
If the facility does not have 208 VAC, 3-phase, 50/60 Hz, 10 kVA power, a customer-supplied step-up or step-down transformer is
required .
3D Systems stocks the following transformers:
DESCRIPTION
3D SYSTEMS PART NO .
Transformer, 230-250 Volt to 208VAC, 10kVA, 60Hz, 3PH
134005
Transformer, 460-500 Volt to 208VAC, 10kVA, 60Hz, 3PH
134006
Transformer, 385-415 Volt to 208VAC, 10kVA, 50Hz, 3PH (EU Version)
134007
•
If you purchase a transformer from a supplier other than 3D Systems, specify a “wye-to-delta” primary-to-secondary configuration.
•
Connect the transformer secondary neutral to the transformer secondary ground .
Caution: Do not connect the transformer secondary neutral to the printer ground .
ELECTRICAL REQUIREMENTS
Refer to the
ProX 500 SLS 3D Printer Facility Requirements Poster on page 33
and
ProX MQC (Material Quality Control)
System Facility Requirements Poster on page 32
for visual layouts of the electrical connections . Refer to the
Chiller
Requirements on page 20
for information on the chiller electrical requirements .
NOTE: The ProX 500 is designed to be connected to primary AC power directly from the facility’s power circuit to the
machine’s input power line filter. This task must be performed by a qualified electrician. The facility’s power circuit
must have a 50A branch protective circuit breaker or fused disconnect with lockout/tagout capabilities .
