CA-PS123A Specifications Notice:
When using a pluggable 16 VAC standard 40 VA transformer:
Maximum
Continuous
Current (no battery attached): 2 amps for 12 VDC on
the Output.
Maximum
Continuous
Current (battery attached): 1.5 amps for 12 VDC on the
Output (battery will be charging when needed).
Using a wire in 16 VAC standard 75 VA transformer:
Maximum
Continuous
Current (no battery attached): 2.5 amps for 12 VDC on
the Output.
Maximum
Continuous
Current (battery attached): 2.0 amps for 12 VDC on the
Output (battery will be charging when needed).
Surge currents need to be taken into account. High current devices like electric
strikes and magnetic locks have surge currents which are usually double the
running current.
The CA-PS123A’s DC output is fused at 2.5 amps.
An electrician is not required for installation of this supply.
NOTE 2: Power Savings
If JP19 and JP20 are placed to the OFF position, all non-essential LEDs will not
indicate thus conserving power. This can be implemented after the system is
installed and approved. See Figure 1 for location of JP19 and JP20.
NOTE 3:
6 Amp Relay Rating
This is the maximum current that can be switched reliably when connected to a
‘NON-Inductive load’ up to 30VDC. Electric strikes and magnetic locks are
considered ‘Inductive Loads’. It is important to have the diode or MOV attached at
the locking device to remove the CEMF pulse that is generated when switching an
‘Inductive Load’. It is advisable to use a 50% switch factor or 3 amps as the
maximum switching current for longer relay life. An external relay should be used
on larger voltage and current requirements.
