- ● Generator Control — Auto start/stop signal with relay dry contact
- ● Modbus RS485 Communication — Remote control & status monitoring
- ● Integrated or Split Type — Flexible installation with separate LCD control module option
- ● Operation: — Generator ready + manual/auto/remote operation
PC Grade Three-Position ATS (CDS2T Type)
Three-position design (I switch-in / 0 disconnection / II switch-in) for applications where a definite OFF position is required. Five controller grades (A to E) from basic to full intelligence with remote control and RS485.
- ● Range: 16A – 630A | 2P/3P/4P | AC400V
- ● Three Working Positions — Common / Both-OFF / Backup, with fire linkage support
- ● 5 Controller Options (A–E) — From basic LED to LCD with communication & timing start
- ● Adjustable Protection — Under-voltage (165–217V) & over-voltage (243–298V) settings
- ● Generator Ready — Relay dry contact for DG auto-start
- ● Manual + Auto + Remote — Operation flexibility with manual rotating wheel
Zero Downtime
Power transfers in just 70ms — lights, machines and critical loads never notice the changeover.
No Manual Intervention
Automatic changeover the moment the grid fails — day or night, weekends or holidays, no operator required.
DG Auto-Start
The generator starts automatically on grid failure and stops when the grid returns — saving both fuel and manpower.
Fire Safety Compliant
Built-in fire linkage control — ready for building safety approvals and fire audits.
Equipment Protection
Under-voltage and over-voltage monitoring on both power sources — keeping your loads safe from unhealthy supply.
Safe Isolation (I–0–II)
A definite OFF position ensures complete safety during maintenance and changeover.
Remote Monitoring
Monitor status, control operations and read fault codes directly from the control room via Modbus RS485.
One Switch, Every Application
One product family from 16A to 630A — a single solution for hospitals, factories and everything in between.
PC Grade Reliability
120kA rated short-circuit withstand — the switch survives even under severe fault conditions.
Flexible Installation
Available in integrated or split type — complete freedom in panel design.
