DTM-1 is a complete AC/DC driver testing machine with THD and efficiency measurement.
Technical datasheet & User guide
DTM-1 is an advanced AC/DC Driver Testing Machine designed for LED Driver, SMPS, Street Light, and Flood Light manufacturers. It provides complete electrical parameter measurement, including THD analysis, real-time efficiency calculation, and automatic Pass/Fail indication — all in a single integrated system.
The machine supports Production Testing, Data Logging, and R&D Applications, making it a complete testing solution for manufacturing, quality control, and product development departments.
Supports 1008 different saved product models.
User can set Upper & Lower limits for each parameter.
Automatic comparison with preset limits during testing.
🟢 Green Tower Light – Pass
🔴 Red Tower Light – Fail
Buzzer ON/OFF selectable:
Buzzer ON for Pass
OR Buzzer ON for Fail (as per user setting)
This ensures fast and error-free decision making on the production line.
Internal Memory up to 32,000 test records (works even without pendrive)
Pendrive support up to 32GB for direct data recording
Automatic logging when pendrive is connected
Real-Time Clock for accurate date & time stamping
Computer interfacing facility available
Software compatible with Barcode Scanner
Production Mode is designed for fast and automatic testing on the production line.
When a product is connected, the system automatically measures all parameters.
Values are compared with preset Upper & Lower limits.
Pass/Fail indication is given instantly through Tower Light and Buzzer (as per user setting).
Data is automatically saved after a selectable time option.
When the product is disconnected, the serial number automatically increases.
When a new load is connected, a new test record is created automatically.
No duplicate entries
No manual counting mistakes
Smooth production tracking
High-speed and reliable testing
Data Logging Mode is used for testing under constant load conditions.
Once load is connected, the system records data continuously.
Recording continues automatically until user disables the function.
Data is saved at a selectable time interval.
