Figure 2 Typical power supply performance
Figure 2 shows the dc output of a 60 W
non-regulated supply.
Fitting a larger filter capacitor will help
to reduce the ripple limits.
1.1.2 Output current and supply voltage
The 200XLV provides a maximum of ±2 A of continuous current, depending on the armature
(AV) and supply voltage (V
DD
).
It requires a supply of at least (8 V + AVmax) to deliver the maximum output current.
The supply voltage can be 12 to 48 V, ±25%, with an absolute maximum of 60 Vdc. NOTE: The
optimum supply is the lowest voltage to supply a fault-free operation.
The short-term current limit overload capability is 150% of the continuous current, for
example, 2 A continuous current, 3 A peak.
