Description

The SDCS-POW-1 is a switched-mode power supply board designed for use in DCS 500 converter modules. Mounted directly on the electronic support framework, this unit functions in a flyback configuration to generate all required internal DC operating voltages for the SDCS-CON-2 main control board and associated electronic peripheral boards. The board features universal system adaptability, operating independently of the specific current or voltage ratings of the drive module. It accommodates standard dual-voltage AC mains inputs, selectable via an onboard slide switch, and includes dedicated jumper configurations to manage encoder power distribution based on the specific control board and I/O board pairing in use.

Features

Switched-mode flyback power supply configuration for efficient internal DC distribution.
Independent operation across the entire current and voltage range of DCS 500 modules.
Onboard selector switch (SW1) for manual selection between 115 V AC and 230 V AC input lines.
Configurable encoder supply voltage output via hardware jumpers X3, X4, and X5.
Dedicated integration terminals for connecting external backup capacitance to extend mains buffering runtime.
Potential-isolated relay output (X96-DO8) featuring an integrated metal-oxide varistor (MOV) for transient protection.

Applications

DCS 500 industrial DC drive converter modules.
Internal DC voltage distribution and control board powering.
Pulse encoder voltage supply management in motor speed measurement loops.

Installation Guidelines

Voltage Verification: Ensure the AC supply selection switch (SW1) is set to match the incoming mains line voltage (115 V AC or 230 V AC) prior to applying power to prevent hardware damage.
Line Potential Hazard: Note that high voltage line potential is present across specific internal components of the board. Disconnect and lock out all primary power sources before servicing.
Encoder Power Configuration: When utilizing an SDCS-CON-2 control board without an SDCS-IOB-3 I/O board alongside a pulse encoder, hardware jumpers X3, X4, and X5 must be manually configured to the proper voltage level matching the encoder's specifications.
Mains Buffering Extension: To extend ride-through capability beyond the standard 30 ms buffer window, external capacitance modules can be wired directly to the designated X95 backup supply terminals.

FAQ

How do I change the input voltage configuration on this power supply board?

The input voltage is changed manually using the onboard slide switch SW1. It can be set to either 230 V AC or 115 V AC to match the incoming utility grid.

Which jumpers control the encoder supply voltage output?

The encoder supply voltage is set using hardware jumpers X3, X4, and X5. They allow configurations for 5 V, 12 V, 15 V, or 24 V outputs depending on the jumper positions.

How can I increase the standard 30 ms mains buffering time?

Additional buffering time can be achieved by connecting external capacitance modules, such as the KJ 2001 unit, directly to the designated X95 backup supply terminals.

Where can I verify the internal DC voltage levels during troubleshooting?

The board features dedicated test terminals for voltage verification: test point X5 B for +5 V, X3 A for +15 V, X3 B for +24 V, and the T 10 heat sink point for the +48 V V2 level.
