Operation

The Exeltech Solid State Transfer Switch

sets a new standard in power density and

alarm capabilities. Its modular design is

available in 3 power levels, 5, 10 and 20KW,

which can be linked together to provide single,

split, and 3 phase systems. The Switches can

communicate on a SNMP protocol via TCP/IP

that provides data on AC volts and amps of

both the primary and secondary sources. If

linked to an MX inverter system it will perform

all the normal functions of the required alarm

card plus communicate DC volts and amps,

all inverter alarms including inverter fail, module

fail, and over temperature. If the inverter is so

equipped, the switch will report both DC Bus

A and Bus B Voltage. Additionally, the switch

can report combined Major and Minor alarms

via SNMP and form C contacts. The minor

alarm is triggered with any alarm, the major alarm is only triggered with complete loss of AC Voltage to the load or when a

complete loss is imminent.

All good to good transfers are synchronous and performed at zero crossing. The switch will operate on the user selectable

primary source until the primary source fails or operates out of limits. It will switch to the secondary source in less than 4 ms

worst case. If the primary returns to normal limits, the switch will wait 15 sec for stabilization, monitor the primary and

secondary source, upon assuring they are in phase, it will switch at the next available zero crossing.

The status of all available alarms, status, and measurements are available via a 2 X 8 LCD display. It is highly

recommended that an Exeltech maintenance bypass switch be used in conjunction with this or any other solid state transfer

switch. This switch can be used with Exeltech inverters or between any 2 AC Sources whether they be inverters, generators

or utility sources.
