The documentation has been prepared with care. This product and documentation are constantly under development. For this reason, the documentation may not always be have been fully checked for consistency with the performance data, standards or other characteristics described. In the event that it contains technical or editorial errors, we retain the right to make alterations at any time and without warning. No claims for the modification of products that have already been supplied may be made on the basis of the data, diagrams and descriptions in this documentation.

Warning! This product has unshielded live 115/230V AC mains parts posing electric shock hazard. Never touch any part of this product when AC power is connected! Always consult experienced electrician for checking power supply installation safety.

Before installing or using SPS product, make sure you have read and understood completely this document and third party document referenced in the chapter 4.

Granite Devices or its personnel will not carry any consequences or give any warranty if safety aspects are overlooked.

2. IntroductionSPS series power supplies are optimized for high peak power loads which ideally match typical position control servo/stepper applications. SPS is capable of delivering up to 3x peak power compared to average output power level without overheating or causing significant voltage drop.

SPS reduces cost and increases efficiency and reliability by skipping voltage regulation which is unnecessary for VSD motor drives.

In addition to this document, user must read also documentation referenced in chapter 4.

4. Original part documentationSPS-600-126 package is based on third party power supply made by Hypex electronics. The power supply card is Hypex SMPS400A400. Before installing the product, read also SMPS400A400 manual from:http://granitedevices.fi/assets/files/SMPS400_Datasheet_R6.pdf

Note: The SMPS400A400 has been originally designed for audio amplifier applications. The purpose of this documentation is to describe how to apply it in servo amplifier application.

5. Electrical installation of SPS-600-126

5.1 Placement of E-STOP switch/contactorIf a circuit breaker (such as E-STOP switch or relay) is placed in the system, it must be placed in the AC input lines (marked as L and N in the wiring diagram).

Warning: never connect a circuit breaker to DC output of SPS.

6. Drive configurationTo allow power supply voltage rise before drive starts controlling motor, it's necessary to set proper voltage limit values in GDtool configuration software. Suggested voltage limit values for SPS-600-126 are presented in the figure below.

7. Frequently Asked Questions1. Do I need to connect regenerative resistor?

You may try drives & machine without regenerative resistors since VSD drives will protect them selves from regenerative over voltage. If you get over voltage faults during deceleration, then install regenerative resistor to at least one drive in HV DC bus.
