Compact Inverter System | 110W Capacity | Emergency Power System

Construction

The EMIN-S inverter is housed in a heavy-duty steel cabinet finished with a white baked-on powder coat that provides excellent scratch and corrosion resistance.

CHARGER

The EMIN-S inverter features a fully automatic, temperature-compensated, dual-mode battery charger that meets UL 924 recharge duty cycle requirements. Charger-only power consumption is rated at 15W maximum (2.5W standby) for the 110W / 125VA model, and 30W maximum (5W standby) for the 220W / 250VA model. A dedicated battery circuit breaker functions as both overcurrent protection and a battery isolator. Standard controls include a momentary test switch and LED status indicators for AC-On, Charge-On, and Inverter-On. Integrated safety circuitry provides AC lockout to prevent battery discharge prior to initial startup and brownout protection that automatically transfers the unit to emergency mode when utility voltage is significantly reduced.

ENVIRONMENTAL

The EMIN-M inverter is rated for installation at altitudes up to 10,000 feet above sea level without derating. The operating temperature range is 68°F to 86°F, with optimum system performance achieved within this range. Temperatures outside the recommended range may affect battery performance and service life. The unit is designed to operate in environments with up to 95% relative humidity, non-condensing.

Emergency Operation

Upon loss of normal utility power, the EMIN-M inverter automatically activates through a solid-state switching circuit, providing a minimum of 90 minutes of emergency power to the connected load while maintaining 100% of the lamp’s rated lumen output for the entire duration. A solid-state low-voltage disconnect protects the battery from deep discharge during extended outages. When normal utility power is restored, the unit automatically transfers the load back to normal operation and the fully automatic, temperature-compensated, dual-mode charger recharges the battery to full capacity in accordance with UL 924 requirements. An integrated brownout sensing circuit ensures proper performance during low-line voltage conditions.

Battery - Battery Backup

The EMIN-S inverter utilizes a sealed lead calcium (SLA) battery system with a 10-year design life. The 110W / 125VA model operates at 24VDC, while the 220W / 250VA model operates at 48VDC. Standard emergency runtime is 90 minutes, based on battery performance at 77°F (25°C). Battery protection includes a low-voltage battery disconnect to prevent deep discharge during extended outages, along with DC overload and short-circuit protection provided by a DC input breaker and fuse for safe and reliable operation.

Operational Temperature

LOAD COMPATIBILITY

The EMIN-S inverter’s clean, true sinusoidal AC output is designed to operate incandescent, fluorescent, induction, and LED lighting loads, ensuring compatibility with common fixture types. Lighting loads are driven at 100% output for the full emergency power cycle, maintaining consistent illumination to enhance occupant egress visibility and safety during power interruptions. Consult the factory for compatibility with other lamp types.

Electrical Components

The EMIN-S inverter operates on 120 or 277 VAC ±10% input at 60 Hz (±2%), with AC line fuse protection. It delivers 120 or 277 VAC output at 60 Hz with a digitally controlled sinusoidal waveform, providing up to 98% efficiency at full rated load. Performance characteristics include ±5% voltage regulation during battery discharge (0–100% linear load), ±0.3 Hz frequency regulation during emergency operation, and less than 3% total harmonic distortion (THD). The unit features a transfer time of less than one second, supports a 0.44 lead to 0.44 lag power factor range, allows 0% minimum loading, and incorporates line and inverter fuse protection for safe and dependable operation.

Electrical Specifications

Installation

The EMIN-S inverter is designed for surface wall mounting and features integral keyhole slots located on the back of the enclosure, allowing for quick, secure, and straightforward installation to standard wall surfaces.
