Power supply
The SPS200 is supplied with 24 V via the barrel connector (grey) or via the 2-position +/- terminal block (green). Turn the switch on (pink). The PWGD LED lights up when the board is powered.
Output terminal block connections
- +VCC: +5 V to +12 V output, configurable with +VCC SET switch (red)
- -VCC: -5 V to -12 V output, configurable with -VCC SET switch (blue)
Enable / Disable
A 3.3 V TTL signal (5 V compatible) can be connected to the DIS terminal block. When the signal is high, the outputs are disabled. If unused, leave unconnected.
Output voltages configuration
The output voltages +VCC and -VCC are set using the +VCC SET and -VCC SET switches, respectively, using the formula:
where SWX = 0 when OFF, SWX = 1 when ON.
Examples
+VCC = 9.5 V (5 V + 1 × 4 V + 0 × 2 V + 0 × 1 V + 1 × 0.5 V = +9.5 V):
+VCC = 6 V (5 V + 0 × 4 V + 0 × 2 V + 1 × 1 V + 0 × 0.5 V = 6 V):
Operating limits
The total ouput power of the SPS200-PN (positive output + negative output) must be kept below 36 W (36 W for the SPS200-PP). In addition to that, the output currents must be kept within the limits defined in the diagram below:
