Notes & safety
Notes: (1) Typical Value at Nominal Input Voltage and No Load.
(2) Test by minimum input and constant resistive load.
(3) Typical Value at Nominal Input Voltage and Full Load.
(4) Input source impedance: The power module will operate as specifications without external components, assuming that the source voltage has a very low impedance and reasonable input voltage regulation. Highly inductive source impedances can affect the stability of the power module. An external input capacitor is recommended for 24VDC nominal input models. We suggest 4.7µF/50V X7R MLCC or Nippon chemi-con KY series, 68µF/100V, ESR 110mΩ or better capacitor. For terminal block versions, the capacitor is included as standard and an external capacitor is not necessary.
(5) Output voltage is adjustable for 10% trim up or -20% down of nominal output voltage by connecting a single resistor between TRIM and +SENSE pins for trim up or between TRIM and –SENSE pins for trim down. To calculate the value of the resistor RU and RD for a particular output voltage see page 5/6.
(6) Maximum output deviation is +10% inclusive of remote sense and trim. If remote sense is not being used, the +SENSE should be connected to its corresponding +OUTPUT and likewise the –SENSE should be connected to its corresponding –OUTPUT.
(7) The CTRL pin voltage is referenced to –INPUT. To order negative logic remote on/off control add the suffix “R” to the model number.
(8) 1. The thermal test conditions for vertical direction are by natural convection (20LFM)
2. Heat sink is optional. See the “Product Options” table for suffix options.
(9) The standard module meets EMI Class A or Class B with external components.
(10) An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. For 24 & 48VDC nominal input models, we recommend connecting one aluminum electrolytic capacitor (Nippon chemi-con KY series, 220µF/100V, ESR 48mΩ) in parallel. For 110VDc nominal input models, we recommend connecting three aluminum electrolytic capacitors (Ruby-con BXF series, 100µF/250V) in parallel.
(11) CASE GROUNDING: EMI can be reduced when you connect the four screw bolts to the shield plane.
(12) This series comes with several different options: Negative remote on/off control, heatsinks, pin length, thru-hole inserts, and terminal blocks. See the “Product Options” table on page 6 for more ordering information.
(13) CAUTION: This power converter is not internally fused. An input line fuse must always be used.
Due to advances in technology, specifications are subject to change without notice.
