Electrical Specification
Conforming to Standards BS/EN60947
DC CURRENT:
S10 25A nominal current flows through L1, L2, M1 & M2
Smooth-BRAKE 60 Amp or 90 Amp high current connections directly
to thyristor diode module.
FREQUENCY:
The unit is for rated 50 Hz.
DWELL TIME:
From operating main contactor to closing DC contactor:
S10
0.5 seconds
Smooth-BRAKE
1 second
TIME RANGE:
S10
braking time range is 0.1 to 12.7 seconds
(270° rotation linear potentiometer)
Smooth-BRAKE
0.2 to 50 seconds
(270° rotation linear potentiometer)
DC VOLTAGE:
The voltage range is up to approx. 160 volts, with the minimum
voltage dependent on thyristor latching current.
DUTY CYCLE
:
S10 Limited by software to 10%. For every second of braking 10 is
added to a register. For every second not braking 1 is subtracted.
Restart is inhibited if the register is above a value of 250.
Note:
if the unit will not start it will be waiting for this register to count
down below 250. The maximum delay is approx. 2 minutes.
Smooth-BRAKE No software limitation of duty cycle. Heat sink rated
for 10 off equally spaced 35 second stops per hour maximum at stated
current.
