ЗУ.240В.5А — NPP "VEL"

ЗУ.240В.5А charger

Purpose:

is designed for use in stand-alone power systems for charging the battery bank.
provides two charging stages:
- Stage I – constant-current charging;
- Stage II – constant-voltage charging.
has built-in protection against battery overvoltage.
can be used as a regulated converter from 220 V AC to (220-280) V DC.
is built to climatic category У, placement category 3.1 per ДСТУ ГОСТ 15150-69, and is designed to operate at temperatures from -25°C to +55°C, relative humidity up to 80% and atmospheric pressure from 650 to 800 mm Hg.
is intended for operation in a non-explosive atmosphere, free of gases and vapours in concentrations that attack metal and insulation, and free of saturated water vapour and conductive dust.
Permissible vibration: 1 to 35 Hz at an acceleration of 4 m/s².

Technical data:

The charger is built as an electronic module housed in a metal enclosure.
Protection rating per ДСТУ ГОСТ 14254
- converter enclosure IP30
- connector IP20
Charger weight, kg, max 2
Mounting position — the heatsink fins must run vertically.
The charger is supplied from a 220 V +10% -15% AC mains supply
Charging current (Inom), 5 A ±0.5.
Nominal battery voltage (Unom) — 260 V.
End-of-charge voltage — 260 V ±3%.
Short-circuit current no more than 10 A.
Protection pickup voltage on output overvoltage: no more than (280±5) V.
Output power at least 1300 W.
Power drawn on the supply circuit with no load: no more than 20 W.
Dielectric strength between the housing and the circuit components, and between the supply circuits and the relay contacts, for 1 min, V AC: 1000.
Switching parameters of the ready-signal relay (NO contacts):
- Electrical life at 2 A, 250 V AC, cos φ>0.5 — 105.
Maximum AC voltage switched by the output contacts: 250 V.
For a higher maximum current (10...20 A), ЗУ.240В.5А units can be connected in parallel.
This charger has no galvanic isolation between input and output.
