1. GENERAL 

The HE-PSU(4.0) is a combined power supply and battery charger designed to be used for fire alarm control 
and indicating equipment complying with EN54-2 and EN54-4. 
 

2. POWER REQUIREMENTS 

The HE-PSU(4.0) requires a mains power supply of 230V AC.  The maximum input current is 2 Amps.  
Mains frequency 50Hz. 
 

2.1 HE-PSU(4.0) Input/Output Electrical Ratings 

Input – 230V AC  
 
Load output - 

19V DC min (battery at minimum), 30 V DC max (mains on) max current 2.5 Amps + 1.5A 

for battery charging. 
 
Maximum ripple 800 millivolts 

 

Battery charging output - 26.4 VDC (at 40°C) 28.9 V DC (at -5°C) 1.5 Amps.  
 
Fault signals -  switched negative open collector (with respect to load positive) current limited 100mA max. 
 

 

Mains fail 

 

 

Battery disconnected (Low battery shut off voltage - 19 V (+/- 1 volt)) 

 

 

Battery low (Low battery warning voltage - 21 V (+/- 1 volt)) 

 

 

Earth fault 

 

 

Charger fault (high output to battery) 

 

 

Fail safe (any one of the above) 

 
These outputs are protected against short circuits.
