Hubbell Single Motor Controller 4015 Specifications

Hubbell Industrial Controls, Inc.
MATERIAL LIST FOR TYPE 4015 SINGLE MOTOR CONTROLLER WITH PROTECTION
TYPE 4015 RECTIFIED DYNAMIC LOWERING
FOR HOIST SERVICE
All the advantages of a dc hoist controller on an
ac crane:
•
Rugged dc series wound mill motor.
•
Reliable dc series wound brake
•
Time-proven dc dynamic lowering hoist
circuit.
•
High-speed hoisting and lowering of empty
hook or light loads.
•
Slow, stable hook speeds hoisting and
lowering with all loads.
•
Reliable dc dynamic lowering with motor
connected as a generator and loaded with
the dynamic braking resistor.
•
"Off point" braking because of spring-
closed dynamic braking contactor.
The complete hoist control system consists of a
power transformer, a silicon bridge rectifier and
the hoist controller with accessories.
•
The power transformer
enclosed, nonventilated (TENV), three-
phase unit with delta connected primary
and a three-phase
secondary.
1 — Two pole main knife switch.
1 — Two pole fused control knife switch.
1 — Electronic overload relay with instantaneous and inverse time trip feature.
1 — 50mV ammeter shunt.
1 — Single pole main line contactor.
4 — Single pole directional contactors with mechanical interlocks.
1 — Single pole spring-closed contactor for dynamic lowering.
4 or 5 — Single pole accelerating contactors.
4 or 5 — Solid state "in-line" timers for acceleration.
2 — Voltage relays.
1 — Undervoltage relay
1 — Power transformer with three-phase delta primary and three-phase wye secondary (for
separate mounting by customer).
1 — Three-phase full wave rectifier bridge with current limiting fuses and surge suppressors.
•
The rectifier unit is a three-phase full wave
bridge
redundancy.
provided by fuses in each leg and a surge
suppressor and snubbing circuit on the dc
side. Output of the rectifier is 300V dc.
•
The hoist controller is standard dc dynamic
lowering controller arranged for operation
from 300V dc power.
components are all front-mounted, front-
removable, and front-wired.
A hoist control system with rectifier output of
360V dc is available as an option.
system operates at higher speeds than the
300V dc system, resulting in a reduced duty
cycle time of about 15%.
