Index of DC Accessories below:

Three-Phase Line Reactors

These reactors are intended for use with the 590 Series three-phase controllers.  They may be used when voltage transformation or supply isolation is not required.  Line reactors:

• Reduce the level of voltage notching on the supply

• Limit total radiated RF interference

• Reduce current spikes in the supply lines during commutation of the SCR bridge.

Highlights

• Compact Design

• UL and CSA approvals through 110A

• Rating for 230 and 480 VAC supplies

• Tab terminal connections
   

Three-Phase Line Reactors for EMC

These reactors are used with EMC filters (see below) for DC controllers that must meet CE standards.

Highlights

• CE approved

• Ratings to 180A
   

Armature DC Contactor Option

For use with 590+ frames 1 and 2, this assembly provides a 3-pole DC loop contactor (includes dynamic braking contact) that isolates the motor from the drive.  Dynamic Braking requires an additional braking resistor kit.

Note:  Do not order with Dynamic Braking Contact Option, contact included in assembly. 

 Highlights

• 1 to 100 Hp
   

Dynamic Braking Resistors

The Dynamic Braking Resistor kits are designed for stopping a motor at full load current from base speed with 2 times motor energy, three times in rapid succession (NEMA ICS 3-302.62 Dynamic Braking Stop Option). 

Dynamic braking provides a low initial cost solution when motor braking can be less precise.  When braking is required frequently in the application (for example, unwinds), a regenerative drive would be a better solution.

Highlights

• Compact design

• Roof/panel mounting

• Horsepower rated for easier selection

• Integral covers for added safety
   

Dynamic Braking Contact

590+ DRV frames 1, 2 and 6+ require a separate dynamic braking contact kit if dynamic braking is required. 

The kits through 100 Hp use a four-pole AC contactor pre-wired to connect to the 590+ terminals.

Above 100 Hp, kits use a single-pole DC contactor that requires 120 VAC control power to close.  The dynamic braking contact must be factory installed and requires a larger panel. 

The Dynamic Braking Contact Kits are designed to meet NEMA dynamic braking requirements (see Dynamic Braking Resistors above).

Note:  When power is lost, the DB contactor will not close on Size 6 or larger drives. 

Highlights

• 500 VDC rated

• Meet NEMA dynamic braking standards

590+ DRV Control Transformer

The 590+ DRV Control Transformer option enables 590+ DRVs to be used in systems that do not use 120 VAC control power.

Highlights

• Operation with 208 through 500 VAC supplies

• Mounts inside the frame 1 and 2 DRVs

• Not needed on DRVs above 100 Hp (at 500 VDC)

• Add -CX suffix to the 590+ DRV part number
   

Blower Motor Starter

The 590+ DRV Blower Motor Starter Option uses a manual motor circuit controller to provide motor overload and branch circuit protection for a single- or three-phase AC blower motor.  The option mounts inside 590+ DRV DC Drives through 100 HP.

Highlights

• UL listing and CSA certification

• Instantaneous magnetic short-circuit protection

• Thermal overload protection with adjustable trip current setting

• Start/stop-reset switching with "tripped"  pushbutton indication

• Normally-open auxiliary contact wired to terminal
   

Controller AC Line Fuse Kits

The AC line fuse kits provide SCR protection for the 590+ Series controllers.  Fuse kits protect drives against transients that may occur in drive supply lines.  Each fuse kit contains three high speed fuses with fuseblocks.

Note:The customer is responsible for complying with all local codes when installing these fuse kits.  SSD Drives will not accept any responsibility for mounting the fuse kits improperly. (b)  The kits do not include panel mounting hardware.

Highlights

• All UL listed or recognized components

• CSA certified

• 300 to 800 amperes

• 500 VAC

• Compression terminal for connections
   

Armature Voltage Feedback Unit 5590

This unit provides a means of isolating and attenuating motor armature voltage to levels compatible with drive input signals to give cost effective voltage feedback.  It is designed specifically for use with analog drives.

Highlights

• Suitable for motor voltages 100 - 550V

• IR compensation up to 11%

• DIN rail mounting

• Bi-directional operation

• Trim output potentiometer
   

Diagnostic Unit 5570

An easy to use hand held diagnostic unit. The 5570 can be used in conjunction with the 514C and 5401 field controller. It gives access to 27 key test points on the drives, rapidly decreasing commissioning time and simplifying trouble shooting.

Highlights

• 3 digit LCD readout

• Access to 27 test points

• Oscilloscope/recorder output
   

Three-Phase Line Filter

The filter provides additional protection against spikes induced on the AC line by DC controllers on 460 VAC systems.  It is recommended when accessories (such as blower motors) are connected to the same main supply as the controller without isolation.  The completely wired fuse kit contains fuses and fuseblocks to provides branch circuit protection for the line filter.

Highlights

• Rating for 230 and 480 VAC supplies

• 1/4 inch tab terminal connections

• Panel mounted
