Load regulation is measured for an output change of 20% to 100%. 2. The outputs of these units may be connected to provide a 5 VDC, 18 VDC, 24 VDC or 30 VDC output. To do this, connect the load across the positive (+Vout) and negative (-Vout) ouputs and float the ouput common. 3. These units do not require external comonents to operate, but the use of an input capacitor (10 F) may enhance performance in some applications. For applications requiring lower output ripple levels, the addition of an output capacitor (4.7 F to 10 F) will typically achieve good results.
