Description
DRA-60 is one 60W AC/DC DIN rail power supply, featuring the adjustable output current. Users are able to easily change the constant output current level, via 1~10Vdc, PWM signal, or resistance. DRA-60 can be mounted on DIN rail TS-35/7.5 or 15; in addition, the width of the unit is only 40mm so it is well suited for installation in a limited spacing. DRA-60 accepts the universal AC input between 90VAC and 264VAC; the efficiency is up to 87% and the entire series can operate, under free air convection, from -30℃ through 70℃.

■ OUTPUT CURRENT ADJUSTMENT OPERATION
※ Built-in 3 in 1 current adjustment function. Output constant current level can be adjusted by applying 1 ~ 10Vdc, 10V PWM signal, or resistance between DIM+ and DIM-.
※ Please DO NOT connect “DIM-” to “-V”.
※ Reference resistance value for output current adjustment (Typical)
| Resistance value | Single Power supply | 10KΩ | 20KΩ | 30KΩ | 40KΩ | 50KΩ | 60KΩ | 70KΩ | 80KΩ | 90KΩ | 100KΩ | OPEN |
| Multiple Power supplies (N=Power supply quantity for simultaneous current adjustment control) | 10KΩ/N | 20KΩ/N | 30KΩ/N | 40KΩ/N | 50KΩ/N | 60KΩ/N | 70KΩ/N | 80KΩ/N | 90KΩ/N | 100KΩ/N | —– | |
| Percentage of rated current | 10% | 20% | 30% | 40% | 50% | 60% | 70% | 80% | 90% | 100% | ||
※ 1 ~ 10Vdc for output current adjustment (Typical)
| Applied Source | 1V | 2V | 3V | 4V | 5V | 6V | 7V | 8V | 9V | 10V | OPEN |
| Percentage of rated current | 10% | 20% | 30% | 40% | 50% | 60% | 70% | 80% | 90% | 100% |
※ 10V PWM signal for output current adjustment (Typical): Frequency range :100Hz ~ 3KHz
| Duty value | 10% | 20% | 30% | 40% | 50% | 60% | 70% | 80% | 90% | 100% | OPEN |
※ Using the current adjustment function can not adjust the output current to 0A. Please refer to the connection method below to adjust the output current to 0A.
