    The Programmable Series RKW (300, 600 and 1500-watt sizes) are RoHS (Reduction of Hazardous Substances) compliant, industrial-grade, single-output power supplies which provide d-c outputs from 3.3 volts to 48 volts from a-c mains 85-265V a-c with power factor correction (PFC) to reduce harmonic corruption of the a-c mains. They are fully enclosed, fan-cooled power supplies. All models feature overvoltage and overcurrent protection and remote error sensing and feature a remote on-off control, remote voltage trimming and master-slave paralleling with a current balance function.
The RKW Programmable Series have been certified by EPRI PEAC’s PQ Star program as SEMI F47 compliant (see Certification). All models conform to EN 60950 following the provisions of the Low Voltage Directive 73/23/EEC and 93/68/EEC for the CE mark. Conducted EMI is suppressed to FCC Class B, VCCI Class B, EN 55011-B and EN 55022-B. The 300 and 600 watt models meet the radiated noise limits of FCC Class B and EN 55022 Class B. The RKW 1500 watt models meet the Class A limits for both conducted and radiated EMI, but can be upgraded to Class B with a noise filter, Kepco P/N 245-0031. Consult factory for details.
RKW Programmable Models are RoHS (Reduction of Hazardous Substances) compliant.
The RKW Programmable Series can be mounted in a 19-inch rack using Kepco's RA 40 Rack Adapter and RAB 39-40RKW3 (300W), RAB 39-40RKW6 (600W), or RAB 40-RKW1500 (1500W), mounting brackets. They can also be mounted on a DIN Rail.
RKW Programmable models can be mixed with your choice of Kepco modular power supplies (e.g., RKW open frame, RKW programmable, RTW, RKE, JBW, HSM, RCW) and packaged in one of our standard rack adapters for a custom power solution you design yourself. Or, if you chose, give us your specs and we'll design it for you.
 
The Kepco RKW Programmable power supplies are more than high-efficiency switch-mode boxes. Beyond the current-share capacity that allows multi-unit paralleling, the 300, 600 and 1500-watt sizes 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 below show for increasing output voltage and decreasing output voltage. 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 the output from 0 to maximum output. A 0-5.5V programming signal will control the RKW to 10% over the rated nominal output. Refer to application notes for additional information regarding programming speed and overvoltage tracking considerations.
All RKW Programmable modules are suitable as DC-DC converters, however note that Safety Agency approvals are valid only for a-c input. DC input voltage range for RKW Programmable models is 110V - 370V d-c.
RKW Programmable are CE Marked per the Low Voltage Directive (LVD), EN60950.
