PS5424 | 24V DC REGULATED POWER SUPPLY PAGE 3
Operating The Unit
This equipment requires adequate ventilation. Please ensure enough breathing space is available for heat
dissipation and install ventilation fan in your rack. The chassis also acts as heat sink unit.
Under normal condition with AC supply available, the output shall be supplied through the AC / DC conversion
circuitry. In the event that power failure occurs, the internal overriding relay shall switch over to back up battery
supply.
In overall, the unit can supply a load of up to 4.5 A max. Only connect loads of low power consumption to the unit.
Other high power drawing equipments such as power amplifiers should be connected separately, or use external
high power relay for back up supply switch over.
PS5424 is built from switching power circuitry thus providing high level of regulation even though incoming supply
may varies.
However, prolonged unstable supply which exceeds the mains operating range may cause damage to the unit or
may affect the output performance.
Remove any short circuit immediately if detected.
Do not modify the output fuse rating to higher amps.
Always ensure correct polarity when connecting. Failure to observe this may cause severe damage and injuries.
