SOLID-STATE POWER CONTROLLER TIMING AT 28 VDC
tle circuit inductance, the current can reach up to 4000% of rated
current even if the Instant Trip level is set as low as 200%!
This possible high level of transient current is short-term. The
lower the circuit inductance, the higher the transient current but
the shorter the transient lasts. In all cases, the wire is protected
since the wire can withstand large overloads for short durations.
The only concern is possible system effects of having large,
short-term transient currents. Generator tripping is unlikely since
the transients are so fast.
HIGH SIDE AND LOW SIDE SWITCHING
Most applications place the circuit breaker in the wire supplying
power to the load, not in the load return wire; this is the ‘High
Side Switch’ configuration. The RP-21200 series are designed
to be placed in either ‘High Side’ or ‘Low Side’ switch configura-
tions.
FIGURE 1 shows both configurations.
Additionally,
because the
STAR Series SSPCs have complete isolation
between the control and power sides, these SSPCs can be used
with either positive (as shown in FIGURE 1), or negative power.
To use these SSPCs with negative power, the configurations in
FIGURE 1 are swapped. That is, the configuration of FIGURE 1
showing ‘High Side Switch’ would be used for low side switching
for negative input power and the configuration in FIGURE 1
showing ‘Low Side Switch’ would be used for high side switching
for negative input power. For either high side or low side switch
configurations, the ‘ground’ symbol in FIGURE 1 would be
replaced with the negative power input, -28VDC for instance, and
the ‘+28VDC’ symbol would be replaced with ground.
SELECTION
All wires carrying current have both continuous and transient rat-
ings for maximum safe operating current. Continuous ratings are
usually expressed in Amps and are dependent on the size of the
wire as well as physical conditions around the wire such as
whether or not the wire is in a bundle. Transient ratings are
expressed as an I2t product, which is a constant. Sometimes,
transient ratings are expressed as a pulse of current for a spec-
ified duration. The I2t constant can be calculated from that data.
Both continuous and transient ratings depend on the allowable
temperature rise of the wire which is dependent upon the type of
insulation on the wire as well as overall system requirements.
Since the STAR Series main function, like a circuit breaker, is to
protect the wire and prevent fire damage, the SSPC must have
lower continuous and transient ratings than the wire’s ratings.
The user must verify that the SSPC’s trip curve falls below the
