40 Watt 24VAC Pure Sine Wave battery backup |
|
To perform the inverse function, converting 24VAC to 24VDC click here. |
Unique systems takes 24VAC input, charges a
battery and supplies 24VAC uniterrupted in case of power failure, Can be used with CCTV, security, and even for 24VAC
irrigation systems. Could even provide battery backup for 24VAC doorbells.
24VDC to 24VAC
inverters are also in development. |
|
| PST-UPS24VAC |
Function: DC/AC Inverter with 24VAC
output |
| Input power |
24VAC allows the UPS to be remotely located by powering it
off the 24VAC system |
| Output power |
40VA continuous (40 Watts) (24VAC 1.6Amps nominal)
50VA
for 1 minute at 50% duty factor( 1 minute above 40VAC, one minute below 40VA |
| |
Important note: Unlike AC/AC transformers this inverter is
actively voltage regulated, so it can be used for any application less than or equal to 40VA. |
| Output Current |
1.6 Amps continuous, 2 amps peak |
| Input voltage |
DC 24VAC Nominal 19VAC to 28VAC |
| Output voltage |
AC 24VAC |
| Output voltage regulation |
± 10% |
| Output wave form |
Pure sine wave |
| Output frequency |
60Hz ± 1% (50Hz available) |
| Standby current |
0.2A, 200 mA typical |
| Battery Charge Current |
1.4 Amps |
Battery Size
Backup time |
This can be used with any size sealed lead acid battery. At
full power the backup time from a 7AH battery would be about 75 minutes |
| Cooling |
Convection cooling, no fan |
| Protections |
Output short
Polarity reverse
Under voltage
input |
| Under voltage protection |
Unit will go into UPS mode when the input voltage falls below
19VAC |
| DC Input |
Screw terminals |
| AC output |
Screw Terminals |
| Isolation |
DC input is galvanically isolated from the AC output, greater
than 100V hipot |
| More options |
Please ask if you need different input voltages, output
voltage, output power, surge protection, connectorization, or form factor. |
Advantages:
 UPS with 24VAC input and 24VAC pure sine wave
output
Makes 24 VAC equipment usable in case of AC failure. 24VAC
inverter can also work with solar or other sources of 12VDC.
Useful for powered security systems, 24VAC
irrigation systems and CCTV systems..
The 24VAC voltage output is regulated, so it is
independent of power drawn. Transformers are not voltage regulated, which makes this inverter a better power source than AC
mains.
This product is in
development. Please call for updates |
