Frequently Asked Questions - RPC-20-SCD Lowell

What is the RPC-20-SCD used for?

The RPC-20-SCD is a remote power controller designed to manage power distribution to multiple devices from a central location. It is commonly used in server rooms, audio/video installations, and industrial settings.

How do I connect the RPC-20-SCD to my network?

Connect the Ethernet port on the rear panel to your local network using a standard RJ45 cable. The device will obtain an IP address via DHCP by default. You can then access the web interface using a browser.

Can I control the outputs individually?

Yes, each of the 8 outputs can be independently turned on/off via the web interface, RS-232 commands, or SNMP. You can also set power-on delays and sequence.

What is the maximum load per output?

Each output is rated for 20 A maximum, but the total load across all outputs must not exceed the maximum power rating of the device (2400 VA at 120 V).

How do I reset the device to factory defaults?

Locate the reset button on the front panel (recessed). Press and hold it for 10 seconds using a paperclip. The device will reboot with default IP (192.168.1.100) and login credentials (admin/admin).

Does the RPC-20-SCD support SNMP?

Yes, it supports SNMP v1/v2c for monitoring and control. You can configure community strings and trap destinations through the web interface.

What type of power cord does it require?

The unit comes with a detachable power cord with a NEMA 5-15P plug for 120 V installations. For other regions, use a compatible cord with IEC C13 connector.

Can I mount the device in a standard rack?

Yes, the RPC-20-SCD is designed for 19-inch rackmount and occupies 1U of space. Mounting brackets are included.

How do I update the firmware?

Download the latest firmware from the Lowell website. Access the web interface, go to Administration > Firmware Update, and upload the file. Do not power off during update.

What are the LED indicators on the front panel?

There is a Power LED indicating the unit is receiving power, and status LEDs for each output showing on/off and fault conditions.

Remote Power Control

actives remote equipment — external trigger required

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).

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 system 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 configured 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 connects 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.

A&E SPECIFICATIONS:

The device for remotely controlling AC power shall be Lowell model RPC-20-SCD, which shall feature a 8.00"L x 3.25"W x 2.75"H steel chassis with black powder epoxy finish, 125VAC 60Hz 20A power rating, NEMA 5-20R duplex outlet, 6 ft. cord with NEMA 5-20P plug, and basic surge protection up to 20,000A. The unit shall require an external trigger for activation (not included).

Closed loop from Fire Alarm
Panel holds RPC ON. When loop
is opened by Fire Alarm Panel, the RPC turns OFF.

outlet ON. Shorting Trigger In
to Com via Fire Alarm Panel contact
closure forces power to outlet OFF.
