| Parameters | SLA-0100-2 | SLA-1000-2 | SLA-1200-2 | Unit |
| Number of channels | 2 | 2 | 2 |
|
| Power input voltage (V dc ) | 9～24 | 9～24 | 9～24 | V |
| maximum output voltage (Vmax)1 | < 21 | < 21 | < 21 | V |
| Maximum output current per channel ( Imax ) 2 | 100 | 1000 | 1200 | mA |
| Maximum output power per channel (P max )3 | 2 | 10 | 10 | W |
| Maximum modulation frequency | 50 | 1 | 1 | KHz |
| Classification maximum current setting | 30, 50, and 100 | 350, 500, and 1000 | 350, 750, and 1200 | mA |
1.The maximum output voltage is 3V lower than the input voltage of the power supply, that is, Vmax=Vdc-3V. For example, if the input voltage of the power supply is Vdc=24V, the maximum output voltage Vmax is (Vdc-3V)=21V;
2.If the channel output voltage is Vd and the output current is Id, then they must simultaneously satisfy: (1) Vd<=Vmax; (2) Id <= Imax； (3) Vd * Id<=Pmax.
3.When both switches are flipped, the Imax of SLA-1200-2 is 1200mA, the Imax of SLA-1000-2 is 1000mA, and the Imax of SLA-0100-2 is 100mA. When both switches are flipped to the bottom, the Imax of SLA-0100-2 is 30mA, and the Imax of SLA-200-2 and SLA-1000-2 is 350mA. When one switch is flipped to the top and the other switch is flipped to the bottom, the Imax of SLA-0100-2 is 50mA, the Imax of SLA-1000-2 is 500mA, and the Imax of SLA-1200-2 is 750mA.
