Specifications
OVERVIEW
| UPC Code | 037332121653 |
INPUT
| Nominal Input Voltage(s) Supported | 120V AC |
| Recommended Electrical Service | DC INPUT: Requires 12VDC input source capable of delivering 125A for the required duration (when used at full continuous capacity - DC requirements increase during OverPower and DoubleBoost operation). For automotive applications, professional hardwire installation with 225A minimum battery system fusing is recommended. AC INPUT: 120VAC |
| Maximum Input Amps / Watts | DC INPUT: Full continuous load - 127A at 12V DC. AC INPUT: 12 amps at 120VAC with full inverter and charger load (6.3A max charger-only) |
| Input Connection Type | DC INPUT: Set of 2 DC bolt-down terminals. AC INPUT: NEMA 5-15P input plug |
| Voltage Compatibility (VAC) | 120 |
| Voltage Compatibility (VDC) | 12 |
OUTPUT
| Frequency Compatibility | 60 Hz |
| Pure Sine Wave Output | No |
| Output (Watts) | 1250 |
| Nominal Output Voltage(s) Supported | 120V |
| Output Receptacles | (2) 5-15R |
| Continuous Output Capacity (Watts) | 1250 |
| Peak Output Capacity (Watts) | 2500 |
| Output Voltage Regulation | LINE POWER (AC): Maintains 120V nominal sine wave output from line power source. INVERTER POWER (AC): Maintains PWM sine wave output voltage of 120 V AC (+/-5%). |
| Output Frequency Regulation | 60 Hz (+/- 0.3 Hz) |
| Overload Protection | Includes 8A input breaker dedicated to the charging system and 12A output breaker for AC output loads |
BATTERY
| Expandable Battery Runtime | Runtime is expandable with any number of user supplied wet, gel or SLA batteries |
| Expandable Runtime | Yes |
| DC System Voltage (VDC) | 12 |
| Battery Pack Accessory (Optional) | 98-121 sealed lead acid battery (optional) |
| Battery Charge | 30A max, 3 step, float for long term maintenance |
USER INTERFACE, ALERTS & CONTROLS
| Front Panel LEDs | Set of 6 LEDs offer continuous status information on load percentage (6 levels reported) and battery charge level (7 levels reported). See manual for sequences. |
| Switches | 3 position on/off/remote switch enables simple on/off power control plus "auto/remote" setting that enables distant on/off control of the inverter system when used in conjunction with optional APSRM4 accessory when used in inverter mode. In AC uninterruptible power mode, auto/remote setting enables automatic transfer from line power to battery power - to maintain continuous AC power to connected loads. |
SURGE / NOISE SUPPRESSION

| Unit Weight (lbs.) | 23.2 |
ENVIRONMENTAL
| Relative Humidity | 0-95% non-condensing |
LINE / BATTERY TRANSFER
| Transfer Time (Line Power to Battery Mode) | 16.6 milliseconds (typical - compatible with many computers, servers and networking equipment - verify transfer time compatibility of loads for UPS applications) |
| Low Voltage Transfer to Battery Power | In AC "auto" mode, inverter/charger switches to battery mode as line voltage drops to 75V (user adjustable to 85, 95, 105V - see manual) |
| High Voltage Transfer to Battery Power | In AC "auto" mode, inverter/charger switches to battery mode as line voltage increases to 135V (user adjustable to 145 - see manual) |
WARRANTY
| Product Warranty Period (U.S. & Canada) | 1-year limited warranty |
Frequently Asked Questions

The APS2012 will run off generator power as long as the output of the generator meets the input requirements for that unit. That requirement is a nominal 120vac at 60hz.

Yes, we offer Pure Sine Wave Inverters. Visit our Inverters product category and filter for Pure Sine Wave Output. A pure sine wave inverter produces a smooth, sinusoidal AC output with a low level of distortion for better performance. A PWM (Pulse Width Modulated) Wave inverter produces a multi-step AC output that approximates a sinusoidal AC output with a higher level of distortion.
