Data centers & critical power
We design and build UL 508A control, monitoring, and power-distribution panels for data centers, critical power, and battery backup systems, and integrate them with the listed switchgear, transfer switches, UPS, and energy storage equipment on your site. One US-based team for engineering, build, and support.
Power switching & distribution
The control, monitoring, and auxiliary distribution panels that sit around your power equipment and tell it what to do and what’s happening.
Control logic, mode selection (manual / auto), and status and alarm indication for utility-to-generator transfer, built around a listed automatic transfer switch or motor-operated breakers in listed switchgear.
Panels for generator start/stop signals, load add and load shed sequencing, and status monitoring, interfacing with the switchgear and the paralleling controllers that ship with it.
Fused or breaker distribution for controls and auxiliaries, control power transformers, redundant 24 VDC supplies, and surge protection, with SCCR calculated and marked on the nameplate.
Control panels for connecting and stepping load banks during generator and UPS testing, with interlocks to the source equipment and clear operator indication.
PLC and VFD panels for CRAH/CRAC units, chillers, pumps, and fans, plus interfaces for leak detection and environmental sensors. Wireless temperature, humidity, and leak sensing can be added with LoRaWAN.
Power meters, PLCs and remote I/O, and gateways (Modbus TCP, BACnet, SNMP) that bring breaker, generator, UPS, and cooling status into your EPMS, BMS, or DCIM, with alarming that names the device and the condition.
Emergency power off and interlock interface panels that collect pushbuttons, relays, and signals and hand them off to the listed equipment that actually opens the power circuits.
Battery & backup
The batteries, UPS units, and inverters are separately listed equipment. We build the UL 508A panels and controls around them and integrate everything into one monitored system.
Control and monitoring panels that interface with the battery management system (BMS) of a listed battery or energy storage system, bringing state, alarms, and trips into your PLC or SCADA.
HVAC and ventilation controls for battery rooms and enclosures, plus hand-off of gas or off-gas detection and fire alarm interface signals to the systems that act on them.
Auxiliary distribution panels for controls, monitoring, HVAC, and lighting around battery and UPS systems, built to UL 508A with SCCR calculated and marked.
PLC, SCADA, and gateway panels for battery, UPS, and generator status, with remote alarming so problems reach the right people quickly.
Critical-load transfer controls, generator start and load-shed logic, and monitoring for manufacturing and process sites that need to ride through a utility outage.
Scope
In plain language: UL 508A is the standard for industrial control panels: control, monitoring, and motor and load control circuits, with a short-circuit current rating (SCCR) marked on the panel. It is not the standard for the large power equipment itself. Low-voltage switchgear (UL 1558), switchboards (UL 891), panelboards (UL 67), transfer switches (UL 1008), UPS units (UL 1778), inverters (UL 1741), battery systems (UL 1973), and energy storage systems (UL 9540, with UL 9540A fire testing) each have their own standards and listings. We build UL 508A labeled control and distribution panels that run, monitor, and switch around that equipment, and we integrate them with the listed switchgear, ATS, UPS, and BESS on your site.
Uptime
Dual-fed or redundant 24 VDC control power where it matters, so one failed supply doesn’t take down monitoring or control.
Schematics, I/O lists, and network and point lists that match what’s installed, kept current through commissioning.
Panels are tested in our shop before they ship, so less is discovered on site.
Alarms that name the equipment and the condition, sent to the EPMS, BMS, or SCADA your operators already watch.
Work in energized, operating facilities is planned step by step around your maintenance windows and change control.
Next step
Send a one-line, a sequence of operation, or a description of the equipment, and we’ll help scope the control and distribution panels around it.
