Recover by resetting the RC terminals. The overvoltage setting tracks the REF voltage. (2) The current limit is rectangular. If overcurrent persists for more than 30 seconds, the output shuts down. Reset by resetting the RC terminals. (3) Bandwidth 100MHz. Ripple and noise will be approximately 1.5 times these values in the operating temperature range -10~0°C. The ripple and noise values tabulated are valid when the output is derated as shown in figure 1 from 50~65°C. PROGRAMMABLE POWER 300-1500 WATTS The new Kepco RKW Programmable power supplies are more than high-efficiency switch-mode boxes. Beyond their wide-range a-c (or d-c) input, beyond their power factor correction (PFC) to reduce harmonic corruption of the a-c mains, beyond the current-share capacity that allows multi-unit paralleling, the RKW are fully programmable by either external voltage (0-5V) or by resistance. The output will track the programming signal with remarkable fidelity as the traces to the right show. Of course, the RKW have large output capacitors so the time constant will depend upon load – and at very light loads or no load, the discharge response will be slow. Note particularly the linearity of the RKW power supply’s response to square and triangular programming inputs. A 0-5V signal programs Output voltage from Output voltage from the output from 0 to maximum output. A 0-5.5V 0V goes to 52.8V (CH2) 52.8V goes to 0V (CH2) programming signal will control the RKW to Rising Time = 8.50 mS Falling Time = 9.92 mS 10% over the rated nominal output.
