1 Model H Free Standing Static Transfer Switch

2 Why choose a model H static transfer switch? Increases power availability. True solid state. Rugged, reliable design. Fast, Intelligent transfers. One touch transfer. Plenty of space for connections. Available in both single and three phase. Built In LAN Web Server and HLI. 5 Circuit breaker array maintenance bypass. Supported current up to 300A.

3 Features Fast, reliable switching Transparent transfer – less than ¼ cycle. Solid state devices are far superior to their electro-mechanical equivalents. Up to 20kA/ 600Amp fuse less SCR modules. Triple redundant internal power sources.

4 Features Safe to Operate Protective cover. Maintenance bypass via a 5 x circuit breaker array. Mechanical interlock.

5 Features Real time monitoring Simple MIMIC status. LCD shows input/output voltage and current. Visual warning during alarm conditions. Ethernet web server.

6 User Interface Actual LCD is blue back lit display with white characters. Mimic Display contains bi-color green/red LEDs.

7 LCD Display LCD Screen can show Status and Alarms. Variables. Event list (200 events). Setting and calibrations. Ethernet options.

8 Features Multiple communications options Ethernet. alerts. 5 relay outputs. 2 control inputs.

9 User I/O & Controls Multiple communications options From Ethernet (IEEE BaseT) SNMP MODBUS HTTP - Web server Alerts. 5 relay outputs. Pin 10 to 12 General Alarm Pin 6 to 8 RLY-O/P Not in Synch Pin 2 to 4 RLY-O/P Overloaded Pin 1 to 3 RLY-O/P ON A Pin 5 to 14 RLY-O/P ON B 2 control inputs. Pin 13 to Pin 7 Remote Transfer to S1 Pin 11 to Pin 7 Remote Transfer to S2

10 Features Programmable logic control Fast internal communication. All variables are easily set in software. Constantly monitors for alarm conditions. Intelligent transfers.

11 Features Flexible input/output configurations Entry through either top or bottom. Bolt connecters allowing for universal connections up to 95mm 2. Plenty of space for connections.
