LS Series Technical Details & Options

Sound Pressure [SPL db(A)] is all octave band frequencies at a distance of 10 feet using a propagation of 1/8 spherical. These are calculated values and should be used a guideline only.

NOTE: Specifications subject to change.

The Automatic Load Level Controller [ A ] will add/subtract load bank load in response to dynamic power fluctuations of the connected building load. It utilizes the load bank as a “supplemental load” for maintaining a minimum load on the power source. Customer “transfer of control” contact closure initiates the load bank and time delay load application circuit. A separately supplied current transformer provides the necessary feedback signal for sensing building load.

Regenerative/ Reverse power Load Step Controls [AA] sense forward and reverse power modes. Must be used with Automatic Load Level Controller.

Integral Control Power Transformer [ T ] which delivers the necessary 120 Volt AC, 1-phase, 60 Hertz power required for control circuit operation. Control power transformer is wired to blower motor circuit and is primary and secondary fuse protected.

Local Operator Control Panel [ L ] - The Remote Operator Control Panel is provided as a Local Control Panel which is mounted and wired to the Load Bank Enclosure. 

Digital Power Meter [ M ]: Fully equipped, 3-phase Digital Metering System that measures a standard range of 16 load parameters. Includes RS485 (Modbus protocol) for remote reading - compatible with PC, PLC, and data loggers. See additional details at: http://www.multitek-ltd.com/HTMs/M800/M850.htm.

Horizontal Airflow Discharge [ LB ] units are available up to 500kW.

Pilot Relay Control [P] allows load bank control from external customer control circuit.

Arctic Duty [E] provides for operation down to -40F

Gravity Louver [G] option provides a stainless steel air-gravity louver in place of fixed exhaust hood.
