General Protection/Safety

Protected against continuous short -circuit, continuous overload, continuous open circuit. Protection Class 1 (IEC536), degree of protection IP20

(IEC60529) Safe low voltage: SELV (acc. IEC60950-1)

Status Indicators

Visual: 3 status LEDs (Input, Output, Alarm)

Relay: N.O. contact rated 200ma/50 Vdc

Installation

Fusing -Input

Internally fused

-Output

Outputs are capable of providing high currents for short periods of time for inductive load startup or switching. Fusing may be required for wire/loads

if 2x Nominal O/P current rating cannot be tolerated. Continuous current overload allows for reliable fuse tripping.

Mounting

Simple snap-on to DIN TS35/7.5 or TS35/15 rail system.

SDN-C Specifications (Single Phase)

1. Not UL listed for DC input.

2. Input current ratings are conservatively specified with low input, worst case

efficiency and power factor.

3. Losses are heat dissipation in watts at full load, nominal input line.

4. 24-28 Vdc adjustable guaranteed at full load.

5. Ripple/noise is stated as typical values when measured with a 20 MHz, bandwidth

scope and 50 Ohm resistor.

6. Peak current is calculated at 24 Volt levels.

7. All models except the 40amp unit are capable of parallel operation by use of a

jumper pin, accessible by the end user. 40 amp unit will have active current sharing

signal.

8. Contact tech support for operation at -25oC.

9. Demonstrated through extended life test.

10. SDN 40-24-100C only = Output signaling terminal block features (Shut down,

Power Good, Current Monitor, Current Balance, signal GND).
