Product Description:

The DCPS-1 is a regulated DC power supply manufactured by Okuma and assigned to the DC Power Supplies series. It converts incoming alternating current into a steady internal link that feeds servo amplifiers and spindle inverters, making it a critical element in automated machining cells. By maintaining a fixed bus, the module ensures each controlled axis receives consistent power for coordinated motion, tool positioning, and rapid deceleration during programmed cycles.

This supply supports up to 2 axes, so two drive units can share its bus without additional converters. Mains connection is specified for 200 VAC at 36 A, and the input is rated for three-phase operation, which is typical in industrial control panels. Internally, it establishes a link voltage of 300 VDC, giving the amplifiers the headroom needed for fast torque transients. Five check test points allow charge, reference, and fault lines to be measured with a meter. Seven front LEDs show the status of PS, MCON, discharge, low-voltage, high-voltage, phase-loss, and over-discharge events, allowing quick visual diagnosis during operation.

A dedicated over-energy circuit opens at 430 VDC, while an under-energy cutoff engages at 220 VDC, protecting downstream inverters from dielectric stress and undervoltage reset conditions. During shutdown, a 100K ohm 2W discharge resistor bleeds the capacitors, and a spring-loaded push switch can speed this process when immediate discharge is required. The housing measures 22 × 8 × 12 in, allowing it to fit a standard control cubicle alongside memory boards and contactors. A set of five screw terminals provides straightforward bus connections, and the front indicator row keeps operating status visible without additional external devices.
