Single-Phase Central Lighting Inverters Catalog Number Comments Application Designed for indoor installation in commercial or industrial applications. Operation When normal utility-supplied power is present, the LSN model central lighting inverter provides load-side line conditioning with "brownout" protection, and charges the system batteries when required. When utility-supplied power is interrupted, or the voltage varies from predetermined limits, the system will automatically and instantaneously transfer to emergency mode without interruption to connected loads. DC battery-derived emergency power is inverted to AC power and supplied in a pure sine wave output form for 90 minutes (standard run time). A low voltage battery disconnect circuit prevents “deep discharge” damage to the batteries during prolonged power outages. When normal power is restored the system will automatically restart, providing power to connected loads and recharging the batteries. The charging circuit will bring the batteries to full recharge within UL time standards. Construction The LSN cabinet is constructed of steel, finished with a light gray paint and features locking cabinetry and password-protected user interface for security. Louvers at front and top of cabinet allow venting. ORDERING GUIDE Series LSN Central Lighting Inverter S = 10-year Sealed Lead-Calcium G = 20-year Sealed Lead-Calcium N = 25-year Nickel- Cadmium Output Circuit Breaker Ampere Rating (7) Output Circuit Breaker Type Blank = Normally On N = Normally Off Requires a provided external transformer for 208VAC or 240VAC input. 277 and 347VAC input only. Other voltages available. Consult factory. External transformer may be provided. Loading may not exceed 50% of the system’s total rating on any 120VAC leg. Normally On circuit breakers: a maximum of 14 monitored, single pole positions or 20 unmonitored, single pole positions may be specified.
