The SynQor UPS-1250 Series is an advanced technology military-grade uninterruptible power supply (UPS) designed to provide reliable power in harsh environments. It utilizes lithium polymer batteries and highly efficient power electronic circuitry to achieve high power levels and extended battery run-times in a low-profile, low-weight, rack-mountable package. The UPS provides voltage and frequency conditioning, electrical isolation, and power flow smoothing between its power inputs and outputs, ensuring battery-backed-up power when other sources are unavailable.
Function Description:
The UPS-1250 Series operates on a true on-line double conversion topology, protecting the load from spikes, noise, surges, brownouts, and blackouts from input power sources. It also smooths load transients and nonlinear load profiles, preventing disturbances to input power sources. Power transfer between sources is seamless, ensuring no disruption in output voltage.
The UPS can draw power from a wide range of AC input voltages and frequencies (80-265 Vrms, 47-800 Hz) or an optional 28 V nominal DC input. AC input has priority over DC input. It provides up to 1250 W of DC output power across up to three DC outputs. The main high-voltage DC output (DC3) is user-adjustable from 25-325 V (default 270 V) and supplies up to 1250 W. An optional DC2 output provides up to 1250 W at a fixed 24, 28, or 50 V. An optional DC1 output provides up to 500 W at 12 V, 15 V, 24 V, 28 V, 40 V, or 50 V. DC1, DC2, and DC3 outputs are isolated from each other.
A communication/control port allows monitoring and control by a host computer system, with front panel LEDs and an audible alarm providing status information.

Withstands harsh mechanical acceleration, shock, vibration, temperature and pressure variations, and exposure to water, salt, sand, and dust (MIL-STD-810G compliant).
- Operating Temperature: -20 °C to +55 °C.
- Cooling: Redundant, waterproof fans on the rear panel.
- Communication: RS232 serial port (115.2k baud), logic-level I/O, and optional Ethernet port (web and SNMP interfaces).
Usage Features:
- Set-Up: Requires proper connection of chassis ground, output cables (with correct polarity), USER I/O cables, and input cables (with correct polarity). An overcurrent protection device is recommended for the DC input circuit. The AC BREAKER on the rear panel should be in the OFF position during setup.
- Start-Up: With AC or DC input present, the ON/OFF switch LED will be amber. Momentarily pushing the ON/OFF switch upward enables outputs, and the LED turns green. The UPS can also perform a "COLD START" from the internal battery if no input power is available.
- Shut-Down: Pushing and holding the ON/OFF switch downward for 1 second disables outputs and shuts down the UPS. The LED turns amber (or off if no input power).
- DC3 Output Voltage and Current Adjustment: User-settable via web page or RS-232 interface. Values are stored in non-volatile memory.
- Hot Swapping Battery Pack: The battery pack can be removed and replaced without disrupting power delivery to the load, provided an input power source is available. If operating solely on battery, removal will cause shutdown.
- Multiple UPS Configurations:
- Higher Output Power: Combine DC3 outputs in parallel (up to 32 units) using configuration cables for digital current sharing (±3% accuracy). DC2 outputs can be combined in parallel (up to 3 units) using droop share (±5% typical, ±10% worst-case accuracy). DC1 outputs are not parallelable without external diode-ORing devices.
- N+M Redundancy: DC3 outputs provide N+M redundancy with an ideal diode, preventing power circulation and ensuring load sharing.
- Balanced Load for 3-Phase Systems: When three UPS units are used with parallel DC outputs, each UPS AC input can connect to a different phase of a 3-Phase source, balancing the load within ±5% (DC3) or ±7% (DC2).
- On/Off Control - Parallel Systems: Configuration cables enable synchronized start-up, shut-down, and fault recovery for parallel systems. A "SYSTEM DISABLE" command via RS-232 is used for coordinated shutdown.
- Input/Output Cable Connections While Operating: Input and output power cables can be connected or disconnected while the UPS is operating, without harming the UPS or disrupting power delivery to the load. However, arcing may occur, especially with high current DC input cables, which can degrade connectors. Connecting new loads to an active output may cause momentary voltage disruption if a large surge current is drawn.
Maintenance Features:
- Battery: Lithium polymer battery cells require no regular maintenance or recharging to prevent degradation. Storage temperature range is -40 °C to +65 °C.
- Fans: Sealed bearings in the rear panel fans require no maintenance.
- Cleaning: The unit's electronics and battery pack are in sealed, weatherproof chambers. Cleaning can be done with soap and water or Isopropyl alcohol and water mixture using a soft cloth. Connector covers should be installed if cables are removed to prevent liquid ingress. Avoid excess liquid on the AC BREAKER switch. Do not immerse the unit in water.
- Trouble-Shooting Guide: Front panel LEDs (16 on the battery pack, 1 above the ON/OFF switch) and audible alarms provide diagnostic information for fault conditions. The manual provides a detailed table linking LED indications and alarm patterns to possible problems and solutions (e.g., input power issues, output overload, fan degradation, battery temperature, battery pack connection).
- No User Serviceable Parts: The UPS has no user-serviceable parts. Only factory-trained personnel should perform repairs. Do not remove covers or open the battery pack.
