The IOTA ILB2H CP20 HE SD HV is a UL Listed emergency LED driver designed for both field and factory installation, providing reliable performance for fixtures equipped with 40–250 VDC Non-Class 2 LED lighting loads. This versatile unit supports both normal and emergency operation, automatically switching to emergency mode during a power failure to operate the existing fixture for a full 120 minutes. The driver integrates a battery, charger, and converter circuit within a single compact enclosure, utilizing a flexible conduit for easy wiring to the fixture and test accessories. Its patented Constant Power design ensures the rated output wattage is maintained across the entire battery runtime, delivering consistent illumination even as battery voltage declines. The unit employs lithium battery technology to reduce overall weight and size and includes automatic monthly and annual self-testing functions as standard. Status and diagnostics are communicated through an illuminated single-piece test accessory, which can be mounted up to 25 feet from the unit for convenient monitoring.
The ILB2H CP20 HE SD HV delivers 20 watts of constant power to the LED array for the full 120-minute emergency runtime, with an output range of 40–250 VDC. Its auto-sensing Non-Class 2 output adjusts automatically to accommodate a wide variety of LED forward voltage designs, ensuring compatibility across diverse fixture types. The unit is particularly well-suited for applications requiring elevated mounting heights or high-bay fixtures due to its high emergency output, which maintains consistent illumination levels without degradation. The driver also satisfies FEMA, Canadian, and other regulatory two-hour runtime requirements, providing reliable performance for life safety applications.
Safety and regulatory compliance are key features of the ILB2H CP20 HE SD HV. The unit is UL 924 Listed for use in both the U.S. and Canada, meets or exceeds NEC, IBC, and Life Safety Code emergency lighting requirements, and is certified for CA Title 20 energy efficiency standards. The AC-activate circuitry simplifies installation by eliminating the need for manual battery connection, while the maintenance-free LiFePO4 lithium iron phosphate battery reduces space requirements and supports high-temperature operation. The driver is housed in a durable galvanized steel enclosure, suitable for plenum spaces, damp locations, and enclosed or gasketed luminaires, and is fully RoHS compliant. A remote-mountable single-piece test switch and charge indicator provide convenient status monitoring up to 25 feet away. The unit is backed by a five-year warranty and offers a 5–7 year battery life expectancy with a full 24-hour recharge cycle.
From a technical perspective, the ILB2H CP20 HE SD HV accepts a universal AC input voltage of 120–277 VAC at 50/60 Hz, with a maximum input current of 0.065 A. Its output voltage ranges from 40–250 VDC, delivering a constant 20 watts of power at an output current of 0.08 A (@250 VDC) to 0.5 A (@40 VDC). The driver maintains a high power factor of ≥ 0.99 and meets ANSI/IEEE surge protection standards (C62.41.2-2002), with total harmonic distortion under 10% at full charge and EMI compliant with FCC commercial limits. Operating temperatures range from 0° to 55° C, making it suitable for a wide variety of environmental conditions.
The ILB2H CP20 HE SD HV combines reliability, efficiency, and ease of installation with features such as constant power output, auto-adjusting voltage range, high illumination output, and self-diagnostic capabilities. Its robust construction, compliance with life safety codes, and long battery life make it a dependable solution for emergency lighting applications across commercial, institutional, and high-bay environments.
