Need help selecting a Stepper System?
Use our selector tool to configure and order.

Linear power supplies provide DC power with fused overcurrent protection, and an auxiliary 5VDC supply to power control logic. Switching power supplies are suitable for applications without large fluctuations in load, or aggressive deceleration or regen requirements. Optional regen clamps and braking resistors are available to help dissipate excess regeneration energy.

Complete SureStep Stepper Systems Overview

SureStep Linear Power Supplies

These unregulated linear power supplies offer full load outputs of 32 VDC/4A, 48 VDC/5A, 48 VDC/10A, 70 VDC/5A; and are perfectly suited to power SureStep stepper drives and stepper motors.

STP-PWR-3204 (32 VDC @ 4A)
STP-PWR-4805 (46.5 VDC @ 5A)
STP-PWR-4810 (46.5 VDC @ 10A)
STP-PWR-7005 (70 VDC @ 5A)
120/240 VAC selectable input
32V, 48V, 70V DC output models available
Linear power supplies are much less susceptible to regeneration from the motor than switching supplies
All models have additional 5VDC, 500 mA regulated logic supply
Fusing included for both incoming AC and outgoing DC
5V supply has electronic overload protection

SureStep power supplies start at
$132.00
(STP-PWR-3204)

SureStep Stepper Power Supplies Overview

RHINO Switching Power Supplies

RHINO PSBx switching power supplies have been tested and are now recommended power supplies for the SureStep drives. If regeneration is a problem, a regen clamp may be needed in more cases with a switching supply than a linear power supply.

PSB12-xxx (12 VDC)
PSB24-xxxS (24 VDC)
PSB48-xxxS (48 VDC)
Universal input voltages,
PSB Series - 120/240 VAC / 120�375 VDC

RHINO Power Supplies Overview

SureStep Regen Braking Accessories

In most stepper systems, a regen clamp (available as optional accessories) is often required to limit increased power supply bus voltage when the motor is decelerating under load.

Features

Built-in 50W power resistor for more continuous current handling
Mounted on a heat sink
Voltage range: 2480 VDC; no user adjustments required
Power: 50W continuous; 800W peak
Indicators (LED):
- Green = power supply voltage is present
- Red = clamp is operating (usually when tepper is decelerating)
Protection: The external power supply is internally connected to an "Input Diode" in the regen clamp that protects the power supply from high regeneration voltages.
