4.1 Regulated and Unregulated Power Supplies
Both unregulated and regulated power supplies can be used to power the ICR
actuator. Unregulated supplies can be a better choice depending on the application
as they have a larger output capacitance, which makes them better energy
absorption sources. They are a good choice for applications that require aggressive
acceleration as they can supply peak currents without faulting and will not trip
on high voltage. However, unregulated power supplies do not have over voltage
protection and care must be taken not to exceed the maximum voltage of the
actuator by using a shunt regulator, and proper fusing to prevent excessive loading
of the supply.
Regulated supplies can be used, but additional measures may need to be taken.
To prevent regenerative energy from reaching the supply, a blocking diode and
capacitor, appropriately sized for the application, should be installed. In addition,
a shunt regulator may be needed to dissipate excess energy. The shunt regulator
available from Tolomatic (see page 4-4) has the appropriate bus capacitance,
requiring only the use of a blocking diode.
The ICR SV1B Basic and SV1P Plus actuators are intended to run off of an isolated
DC power source. The power supply that is required will depend on the application.
A 48V supply will allow the actuator to operate at maximum speed. A 24V supply
will result in approximately half the rated velocity. Input current will depend on the
actuator power needed in the installation. If operating more than one actuator on
the same power supply, add the required power supply rating for each actuator.
4.1.1. Power Supply Sizing Guidelines
Use the following tables to help determine the proper power source voltage for an
application or call Tolomatic at 1-800-328-2174 or 763-478-8000 for assistance.
NOTe:
Green numbers indicate power supply required in Watts for the given speed
and thrust indicated at outside margins.
WARNING!
All installations should
provide a means for a
hardware emergency
stop that removes power
from the actuator in an
emergency condition.
The actuator emergency
stop function should
not be relied on when
safety is required. It
is recommended to
disconnect only the + bus
power and keep the power
ground line connected.
