REMOTE POWER CONTROLS can be combined with a variety of switches or sequencers for an intrinsically
safe, low voltage method of controlling AC power to equipment at remote locations. Controlling power
distribution without directly accessing equipment minimizes the potential for unauthorized access, while
simplifying activation and deactivation of equipment.
Note: RPCs require an external trigger for activation (order separately).
Ideal for Lowell switches featuring main-
tained closure (order separately):
RPSB-P Black wall plate w/rocker switch
RPSW-P White wall plate w/rocker switch
RPSW-KP White wall plate w/key switch
RPSB-R Rack panel w/rocker switch
RPSB-KR Rack panel w/key switch

FEATURES
CHASSIS: Steel chassis (8.00"L x 3.25"W x
2.75"H) with black finish and mounting holes.
POWER:
• Power Rating: 125VAC 60Hz 20A
• Outlets: NEMA 5-20R duplex
• Attached Cord: 6 ft. cord with NEMA 5-20P plug
SURGE PROTECTION:
• Maximum Surge Current: 20,000A
• VPR (UL 1449-3): 400V
• Response Time: 1 nanosecond
• EMI/RFI Noise Reduction: 20dB@100kHz
• Protection Mode: Line to Neutral
• Ground Contamination: None
ACTIVATION: The RPC must be connected to an
external control for activation and deactivation
(choose one):
• Dry Contact Closure: Connect to SPST switch,
power sequencer, or independent control sys-
tem with dry contact closure.
: Contact Coil Rating
- Voltage: 24VDC
- Current: 37.5mA
• Voltage Trigger (5-24V AC or DC 5mA):
DSP connection.
ORIGIN: Made in the U.S.A. with global components
THIRD PARTY APPROVAL: ETL Listed to
UL60065 (U.S. and Canada)
INSTALLATION: The RPC is typically installed
near the equipment to be controlled. Low voltage
cable is run from its terminal strip to a control
switch (or other control method).
• Systems can be configured with multiple RPCs
controlled by a single "Maintained Closure"
switch or voltage trigger source.
• Systems can also be congured with a single
RPC controlled by multiple "Momentary Closure"
switches and Lowell's MSM2 module (which
converts momentary closure to maintained).
COMPATIBLE DEVICES: (order separately)
• SPST Switch (RPS Series): Low voltage wall-
mount or rack-mount switch:
– Switch with maintained closure con-
nects directly to RPC.
– Switch with momentary closure requires
Lowell conversion module MSM2
placed between the switch and RPC.
• POWER SEQUENCER (SEQ SERIES): A low
voltage sequencer can be used with the RPC
for time-delayed activation and deactivation
of connected equipment. Lowell standalone
sequencers will require a switch for activation,
while Lowell rack-mount sequencers include a
switch. See product spec sheets for information.
