Notes
1. Input current measured at nominal input voltage.
2. Typical values.
3. For optional version fitted with DIN Clip add suffix ‘-D’ e.g. DTJ2024S12-D.
4. For optional factory fitted heatsink add suffix ‘-HK’ e.g. DTJ2024S12-HK or
DTJ2024S12-HKD with DIN clip.
5. Input current is typically 2.0mA at nominal input voltage when output is remotely
turned off.
6. Per output.
