RTW (KEPCO)

Kepco’s RTW series are RoHS compliant, general-purpose, L-chassis, single-output power supplies. They are available in 50, 100, 150 and 300 watt power levels. Their small size and very low profile allows the RTW to be fitted into small spaces. They feature full safety compliance to international standards and have suppressed both conducted and radiated EMI to FCC Class B levels. Power Factor Correction (PFC) is standard, with the input power factor typically equal to 0.99. This minimizes the potential for the introduction of distortion on the a-c mains as the power supply’s input conduction takes place over the entire a-c cycle. A green power-on LED provides visual evidence of operation. An isolated remote ON-OFF control is built-in, as is remote error sensing. (A 4-wire Kelvin connection on the load reduces the losses in the d-c load wires.) RTW may be operated in series for increased output voltage. The output of the 50W and 300W models is current limited with a “square type” current limit circuit. The 100 and 150W models have a “hiccup” mode, in which the power supply periodically checks to determine if the overload has been removed and when it senses that it has, the output voltage is automatically restored. Output voltages are user-adjustable. Current limit is factory set. When an overvoltage is detected, the output voltage shuts down. Reset by using ±RC terminals. An interval of 30 seconds before restarting is required if input power is switched off. Only the 300W models with the suffix “KC” include an aluminum cover. The 50, 100 and 150W models are open frame with an optional Vox installed cover (add suffix “C” to the model number).
