The Samlex STEP 20 is a high efficiency switch-mode step-UP DC-DC converter that converts an input voltage of 12 VDC nominal (range 9 VDC to 18 VDC) to a highly regulated output voltage of 24 VDC nominal at 20 Amps. See the details tab for more information.

The STEP 20 converter is non-isolated (no galvanic isolation between input and output) and meant for use in negative ground systems. Features include High efficiency switching regulator, Very low self consumption - less than 5mA, Small size and lightweight, Non-isolated input and output design for higher efficiency, Protected against overload, short circuit, reverse polarity, and high voltage and transient suppression on input side.

  • Output noise and ripple: < 50mV RMS
  • Isolation,: input to output: No Common Negative
  • Isolation, input / output to chassis: Isolated
  • Temperature rise after 30 minutes of operation at full load: 30 degrees C @ 20 degrees C ambient
  • Type of cooling: By convection (No Fan)
  • 12V input side fuse (internal): 80A (2 x 40A)
  • 12V input side fuse (external): 70A (2 x 35A) (Not supplied)
  • 24V output side fuse (internal): No Fuse
  • 24V output side fuse (external) 20A (Not supplied)
  • Reverse polarity on input side: External / Internal input Side Fuse will blow
  • High voltage and transient suppression on input side: Will blow input side fuse at continuous input voltage > 40V. Also protects against load dump.
  • Over current: Short Circuit Proof. External 20A fuse will blow
