Three Phase Full Wave Fully Controlled Fully Isolated DC Drive |
|
 |
Six Thyristors in bridge configuration
Range : 3 HP to 200HP (Three Phase)
Any Analog Reference Signal field selectable i.e 4-20
mA, 0-10 VDC, 0-5 DC, 0-20 mA, 2K to 100K Pot. (Manual speed
setting)
Armature voltage / Tacho meter feed back field selectable
Any Tacho meter (AC / DC) of any voltage field selectable
Tacho meter polarity insensitive
Incase of Tacho failure Drive will automatically transfer
to armature feed back
Only visual indication of “ Tacho Loss ” will
glow
Digital Firing : For, Input phase current balancing
Input Phase Sequence insensitive
SPP, UV, OV, CT adjustable, Current trip relay output
Linear Tension Control (Unwinder/winder application)
For Constant Current (Taper Tension) / Constant Tension
application
Max. Speed, Current limit, acceleration adjustable
Indication : Run, Stop, Field OK, Field fail, Current
Limit, Tacho Loss, SPP, UV, OV, CT
Inbuilt Snubber Protection for high dv/dt protection
