Operating the DPS-1 

The DPS-1 is designed to operate without manual intervention. It is equipped with a visual 
and electrical indication/alarm that continuously monitors the input and output voltage  

6.1

 

Voltage drop compensation 

The power supply can be adjusted to compensate the voltage drop in the wiring between the 
DPS-1 and the load. Examples of voltage drop can be found in the following table. 

Wire cross section 
(mm

2

Length (m) 

Current (A) 

Voltage drop* (V) 

0.75 

1.25 

1.00 

0.9 

1.50 

0.6 

2.50 

0.35 

* The voltage drop is based on threaded copper wire at 20ºC  

The voltage drop formula is: V = length x current x cable resistance x 2  
(thus the double current or double length will also double the voltage drop. 

Example: 1.5 mm2, 5 m, 5A => V = 0.6 V 

Setting: 24.0 + 0.6 = 24.6 V 

6.2

 

Visual and electrical monitoring 

DPS-1 has two monitoring types: 

  Electrical monitoring: DPS-1 has a dry contact “DC OK” relay output which is closed 

(energised) under normal operating conditions (no failure).  

  Visual monitoring: A green LED provides visual indication of the DPS-1 operational 

status. 

The behavior of the LED and relay is according to the following table:
