Power Supplies and Regen

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.

SureStep Power Supplies

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 $125.00 (STP-PWR-3204)

RHINO Power Supplies

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 start at $37.25 (PSB12-060)

SureStep Regeneration Clamp

SureStep Regen Braking Accessories

In most stepper systems, a clamp circuit is often required to limit increased power supply bus voltage when the motor is decelerating under load and a regeneration clamp and braking resistor are available as optional accessories. The regen clamp has a built-in 50W braking resistor., and for additional braking power (larger overhauling loads), an optional 100W braking resistor is also available.

Built-in 50W power resistor for more continuous current handling (optional 100W resistor is also available)
Mounted on a heat sink
Voltage range: 24�80 VDC; no user adjustments required
Power: 50W continuous; 800W peak
Wire connection: 6-pin screw terminal block; 12�18 AWG wire
Indicators (LED):
- Green = power supply voltage is present
- Red = clamp is operating (usually when stepper 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. This diode protects the system from connecting the power supply in reverse. If the clamp circuit fails, the diode will continue to protect the power supply from over-voltage.
SureStep Regen Clamp 50W, 24-80 VDC (STP-DRVA-RC-050)
and SureStep Braking Resistor 100W, 10 ohm, encapsulated (STP-DRVA-BR-100)
The SureStep Regen Clamp is $89.00 (STP-DRVA-RC-050)

We probably have a couple hundred of these power supplies throughout our factory and again an excellent success rate. Very durable as some of our systems are not in favorable environments and these Rhino supplies hold up well. Another great value from Automation Direct.
