The SP-3V, SP-3, & SPS-3 are heavy duty self contained, efficient clean with linear performance off-line switching power supplies that are selectable between 12vdc at 3 Amps, and 24vdc at 1.5 Amps.  With the universal AC input, these supplies may be connected anywhere in the world with no plug-in transformer or any alterations.  These power supplies have exceptional brown out capability with operation down to 60vac.  The SP-3V has an adjustable output with no battery charger and is intended to be used where no standby power is required.  The extensive filtering system provides a very clean DC output with linear performance.  All of the supplies are power limited and thermally protected.  All output faults are self restoring.

The SP-3 and SPS-3 both have a precision lead acid battery(s) charger that obtains maximum battery life while providing a 12vdc or 24vdc uninterruptible power supply.  The SP-3 & SPS-3 are protected against Battery(s) reversal, shorting or overloading.

Before connecting load and battery(s), set 12v/24v selector jumpers to the desired voltage.  Caution, damage will occur if jumpers are moved with DC output load or Battery connected.  Confirm proper voltage before connecting devices.

The SPS-3 has the additional supervisory features of a set of form “C” relay contacts that indicates AC power status, and a special electronic circuit that limits the output current to provide class II power limiting and load disconnect when battery(s) is depleted.

AC Input: L, N, G - 3P Orange Terminal block

Safety block with recessed hardware insulation that will accept up to 12AWG

L= Line, N= Neutral, and G = Ground

Optional 3 wire line cord P/N: ................    HA-LC3SZIP

AC Input Rating .............................   90-250vac/50W

      AC Input Operational .....................    60-264vac

AC LED Indicator (Next to AC Input Terminal)

The AC indicator is a bi-color green and red led. 

AC Line Fuse

Fuse:     ...................   GMA-2 5mm x 20mm 2A 250v fast

DC VOLTAGE SELECTOR JUMPER J1

The selector jumper J1 selects the voltage to 12v or 24vdc.  As marked on the PCB, jumping 1&2 and 3&4 sets the supply to 12v.  Jumping 2&3 sets the supply to 24vdc.  CAUTION To prevent damage, remove DC load and battery(s) connections before switching selector J1 jumpers

DC OUTPUTS: ................................ 2P Terminal block

Output voltage Nominal ..........................  12vdc/24vdc

Output voltage Typical  ..................   AC on 13.70/27.40

SP-3V Adjustable  ...........................      12 -13.5vdc

Output continuous current 12v/24v  ..................  3A/1.5A

Current Overload Short Circuit Protection ...............  Yes

Thermal runaway Protection  ............................   Yes

Current Overload and Thermal shutdown will auto-restart without removing load.

SP-3V Class II Power limiting ...........................  Yes

SP-3 Class II Power limiting   ..........................   No

SPS-3 Class II Electronic Power limiting   ..............  Yes

Ambient operating temperature range ........   -30oF to +130oF

Storage Temperature  ........................   -60oF to 190oF

Switching Frequency   ..............................    132KHz

DC LED Indicator (Adjacent to DC Output) ................  Red

Battery Charging: (Header plug marked [–Bat+])

SP-3 & SPS-3 only

The battery charger is precision set to float charge 12v or 24V sealed or wet lead acid batteries.  Two 12v batteries are connected in series for 24V.  A 12” battery cable assembly is provided that plugs from module to battery.  Red (+) 12vdc, Black (–) Neg.

Optional 36” battery cable (1) P/N: ..............   WA-36IBAT

Battery(s), any type of lead acid ............... 12v 4AH-40AH

UL Evaluated with 7AH Battery

Battery(s) PTC self resetting Circuit Breaker ........  3A PTC

Battery(s) Reverse hookup protection  ...................  Yes

To estimate the recharge time in hours for depleted battery(s), multiply the AH rating times 4 (AH x 4).  As an example, a 24v system with two depleted 12v 7AH batteries would take about 28 hours to re-charge.  See http://www.securitypower.com/an3batby.pdf for battery standby selection table.
