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.
